The Okeechobee hurricane, or San Felipe Segundo hurricane, was a deadly hurricane that struck the Leeward Islands, Puerto Rico, the Bahamas, and Florida in September of the 1928 Atlantic hurricane season. As of 2010, it is the only recorded hurricane to strike Puerto Rico at Category 5 strength on the Saffir-Simpson Hurricane Scale, and one of the ten most intense ever recorded to make landfall in the United States.
The hurricane caused devastation throughout its path. As many as 1,200 people were killed in Guadeloupe. The storm directly struck Puerto Rico at peak strength, killing at least 300 and leaving hundreds of thousands homeless. In South Florida at least 2,500 were killed when a storm surge from Lake Okeechobee breached the dike surrounding the lake, flooding an area covering hundreds of square miles. In total, the hurricane killed at least 4,078 people and caused around US$100 million ($1.36 billion 2013 USD) in damages over the course of its path.
The storm was first observed 900 miles (1450 km) to the east of Guadeloupe on September 10 by the S.S. Commack. At the time, this was the most easterly report of a tropical cyclone ever received through ship's radio. A Cape Verde-type hurricane, hurricane analysis in the 1990s determined the storm likely formed four days prior between Cape Verde and the coast of Africa.

As the storm neared the Caribbean, it was already a Category 3 hurricane. On September 12, the strengthening storm passed over Guadeloupe, its eye centering over Pointe-à-Pitre between 1830–1930 UTC, with winds of 140 mph (230 km/h). It then passed south of the other Leeward Islands while continuing to strengthen. Guadeloupe reported a pressure of 27.76 inHg (940 mbar), and a ship just south of St. Croix in the United States Virgin Islands reported it as an even stronger storm with a pressure of 27.50 inHg (931 mbar). On the 13th the storm struck Puerto Rico directly as a Category 5 hurricane, allegedly packing winds of 160 mph (260 km/h); reliable reports from San Juan placed the wind speed at 125 knots (145 mph, 230 km/h), and a report from Guayama placed the pressure at 27.65 inHg (936 mbar). The 160 mph (260 km/h) wind measurement from Puerto Rico was taken by a cup anemometer in San Juan, 30 miles (50 km) north of the storm's center, which measured 160 mph (260 km/h) sustained winds three hours before the peak wind speed was reached; however, the instrument was destroyed soon after and could not be calibrated. This unverified reading was the strongest wind measurement ever reported for an Atlantic hurricane up until that time.
The hurricane was also extremely large as it crossed Puerto Rico. Hurricane-force winds were measured in Guayama for 18 hours; since the storm is estimated to have been moving at 13 mph (21 km/h), the diameter of the storm's hurricane winds was estimated very roughly to be 234 miles (376 km). After leaving the Caribbean, the hurricane moved across the Bahamas as a strong Category 4 hurricane. It continued to the west-northwest, and made landfall in southern Florida at 00 UTC on September 17 (7:00 p.m. local time on September 16). Initially, Richard Gray of the U.S. Weather Bureau was optimistic that the storm would spare the south Florida region. Atmospheric pressure at landfall was measured at 929 mbar (hPa), and maximum sustained winds were near 145 mph (233 km/h). The eye passed ashore in Palm Beach County near West Palm Beach, then moved directly over Lake Okeechobee. Peak gusts were estimated near 160 mph (260 km/h) at Canal Point. The hurricane's path turned northeast as it crossed Florida, taking it across northern Florida, eastern Georgia, and the Carolinas on September 19. It then moved inland and merged with a low-pressure system around Toronto on the 20th.
|Storm Deaths by Region|
The hurricane moved directly over the Leeward Islands in the Caribbean, strengthening as it did so. On the island of Dominica winds were clocked at 24 mph (39 km/h); there were no reports of damages. In Martinique, even further south of the storm's path, there were three fatalities. Guadeloupe received a direct hit from the storm, apparently with little warning; the death toll there was 1200, and damage reports relayed through Paris indicated "great destruction" on the island.
Montserrat, just north of the storm's center, was warned in advance of the storm but still suffered £150,000 (1928 UKP) in damages and 42 deaths; Plymouth and Salem were devastated and crop losses caused near-starvation conditions before relief could arrive. The storm passed to the south of the islands of St. Kitts and St. Croix, which suffered heavy damages to property and crops but no reported fatalities. Nevis did report three deaths due to the storm, though. Damage reports from elsewhere in the Leeward Islands are not available.
The island of Puerto Rico received the worst of the storm's winds when the hurricane moved directly across the island at Category 5 strength. The island knew of the storm's approach well ahead of time; by about 36 hours in advance all police districts were warned and radio broadcasts provided constant warnings to ships. Effective preparation is credited for the relatively low death toll of 312, and not a single ship was lost at sea in the vicinity of Puerto Rico. By comparison, the weaker 1899 Hurricane San Ciriaco killed approximately 3,000 people.
The storm was named the San Felipe II Hurricane because the eye of the cyclone made landfall on the Christian feast day of Saint Philip. It was named "Segundo", Spanish for "the Second", because of another destructive "Hurricane San Felipe" which struck Puerto Rico on that same day in 1876. Since European arrival in the Americas in 1492 all storms and hurricanes were named after the name of the saint of the day the storm hit Puerto Rico. In 1953 that the United States started naming hurricanes by female names until 1978 when both gender names began to be used. Yet it was only in 1960 that hurricanes stopped being officially named after Saints.
San Felipe II is officially classified as Puerto Rico's biggest, worst, and most devastating hurricane to ever have impacted the island. Even though it was the worst hurricane to hit the island, others such as the San Ciriaco Hurricane caused more deaths. The first warning the Island received was by the steamship Commack on latitude 17° north and longitude 48° West. San Felipe entered the island early in the morning of Thursday September 13, with its eye close to Guayama and it traversed the island in a north-west direction, leaving between the towns of Aguadilla and Isabela. The eye of the hurricane made its Puerto Rico crossing in eight hours, moving at about 13 mph (21 km/h). In Guayama, located in south eastern Puerto Rico, the lowest recording of the storm was taken; 27.5 inHg (930 mbar) at 2:30 p.m.
The rainfall recorded on September 13–14, 1928, are records for the maximum of rainfall associated with a hurricane in Puerto Rico within a period of forty-eight hours. In those regions where precipitation is more common place, as in Adjuntas in the Cordillera Central and in the Sierra de Luquillo, the rain was over 25 inches (640 mm), with 29.60 inches (752 mm) recorded in Adjuntas.
The anemometer located in Puerta de Tierra lost one of its cups at 11:44 am on the September 13, just when it had registered a maximum speed of 150 miles (240 km) per hour, a speed that was sustained for five consecutive minutes. Previously the same instrument had measured 160 miles (260 km) per hour for one minute. The city of San Juan was 30 miles (48 km) away from the eye of San Felipe when those measurements were recorded—because of which, at the time, it seemed possible that some estimates of 200 miles (320 km) per hour near the center of the storm were not overdrawn.
There was general destruction through the island, with the towns where the eye passed being swept away. Property damage on the island from winds and rain was catastrophic. The northeast portion of the island received winds in excess of Category 3 strength, with hurricane-force winds lasting as long as 18 hours. Official reports stated "several hundred thousand" people were left homeless, and property damages were estimated at $50 million ($680 million 2013 USD).
In the island there was no building that was not affected. Some sugar mills ("Centrales") that had cost millions of dollars to build were reduced to rubble. Reports say that 24,728 homes were completely destroyed and 192,444 were partially destroyed. Most of the sugarcane fields were flooded, thus losing the year's crops. Half of the coffee plants and half of the shade trees that covered these were destroyed; almost all of the coffee harvest was lost. The coffee industry would take years to recover since coffee needs shade trees to grow. The tobacco farms also had great losses. After this hurricane, Puerto Rico never regained its position as a coffee exporter.
Communications were impacted by fallen trees, landslides, and debilitated bridges. Of the school buildings 770 were destroyed or debilitated. According to some estimates of the day, excluding personal losses, the damages reached ($1.16 billion 2013 USD) and over 500,000 people were left homeless.

The eye of the hurricane passed over much of the island chain as a strong Category 4 hurricane, again causing very heavy damage. As in Puerto Rico, however, authorities in the Bahamas were aware of the hurricane's passage well ahead of time, and preparations minimized the loss of life in the islands. The only report of fatalities was from a sloop lost at sea in the vicinity of Ambergris Cay with 18 on board.
Coastal damage in Florida near the point of landfall was catastrophic. Miami, well south of the point of landfall, escaped with very little damage; Hollywood and Fort Lauderdale suffered only slight damages. In Fort Lauderdale, numerous power lines and telephone wires were downed. Northward, from Pompano Beach to Jupiter, buildings suffered serious damage from the heavy winds and 10 ft (3 m) storm surge, which was heaviest in the vicinity of Palm Beach; total coastal damages were estimated as "several million" dollars. In West Palm Beach, more than 1,711 homes were destroyed, while the Jupiter Inlet Lighthouse's mortar was reportedly "squeezed ...like toothpaste" between the bricks during the storm, swaying the tower 17 inches (43 cm) off the base. Because of well-issued hurricane warnings, residents were prepared for the storm, and the number of lives lost in the coastal Palm Beach area was only 26.
Inland, the hurricane wreaked much more widespread destruction along the more heavily populated coast of Lake Okeechobee. Residents had been warned to evacuate the low ground earlier in the day, but after the hurricane did not arrive on schedule, many thought it had missed and returned to their homes. When the worst of the storm crossed the lake, the south-blowing wind caused a storm surge to overflow the small dike that had been built at the south end of the lake. The resulting flood covered an area of hundreds of square miles with water that in some places was over 20 ft (6 m) deep. Houses were floated off of their foundations and dashed to pieces against any obstacle they encountered. Most survivors and bodies were washed out into the Everglades where many of the bodies were never found. As the rear eyewall passed over the area, the flood reversed itself, breaking the dikes along the northern coast of the lake and causing a similar but smaller flood.
Floodwaters persisted for several weeks, greatly impeding attempts to clean up the devastation. Burial services were quickly overwhelmed, and many of the bodies were placed into mass graves. Around 75% of the fatalities were migrant farm workers, making identification of both dead and missing bodies very difficult; as a result of this, the count of the dead is not very accurate. The Red Cross estimated the number of fatalities as 1,836, which was taken as the official count by the National Weather Service for many years (and exactly equal to the official count for Hurricane Katrina). Older sources usually list 3,411 as the hurricane's total count of fatalities, including the Caribbean. However, in 2003 the U.S. death count was revised as "at least" 2,500, making the Okeechobee hurricane the second-deadliest natural disaster in United States history behind the Galveston Hurricane of 1900. A mass grave at the Port Mayaca Cemetery east of Port Mayaca contains the bodies of 1,600 victims of the hurricane.
Thousands of people were left homeless in Florida; property damage was estimated at $25 million ($340 million). It is estimated if a similar storm were to strike as of the year 2003, it would cause $18.7 billion in damages. The cyclone remains one of three Atlantic hurricanes to strike the southern mainland of Florida with a central pressure below 940 mbar (27.76 inHg), the others being the 1926 Miami hurricane and Hurricane Andrew of 1992.
Limited damage reports are available for the United States outside of southern Florida. The storm caused flooding in North Carolina and brought near-hurricane-force winds and a 7 foot (2.1 m) storm surge to the Norfolk area. Nonetheless, most sources agree that the hurricane caused only minimal damage in these areas.

In Florida, although the hurricane destroyed everything in its path with impartiality, the death toll was by far highest in the economically poor areas in the low-lying ground right around Lake Okeechobee. Around 75% of the fatalities were from migrant farm workers, most of whom were black. Black workers did most of the cleanup, and the few caskets available for burials were mostly used for the bodies of whites; other bodies were either burned or buried in mass graves. Burials were segregated, and the only mass gravesite to receive a memorial contained only white bodies. The inequity has caused ongoing racial friction that still exists. The effects of the hurricane on black migrant workers is dramatized in Zora Neale Hurston's novel Their Eyes Were Watching God.
Improved building codes
In the aftermath of the hurricane in coastal Florida, it became apparent that well-constructed buildings with shutters had suffered practically no damage from winds that caused serious structural problems to lesser buildings. Buildings with well-constructed frames, and those made of steel, concrete, brick, or stone were largely immune to winds, and the use of shutters prevented damage to windows and the interior of the buildings. Coming on the heels of the 1926 Miami hurricane where a similar pattern had been noticed, one lasting result of the 1928 storm was improved building codes.
To prevent a recurrence of disasters like this one and the Great Miami Hurricane of 1926, the Florida State Legislature created the Okeechobee Flood Control District, which was authorized to cooperate with the U.S. Army Corps of Engineers in flood control undertakings. After a personal inspection of the area by President Herbert Hoover, the Corps drafted a new plan which provided for the construction of floodway channels, control gates, and major levees along Lake Okeechobee's shores. A long term system was designed for the purpose of flood control, water conservation, prevention of saltwater intrusion, and preservation of fish and wildlife populations. One of the solutions was the construction of the Herbert Hoover Dike. Today, concerns related to the dike's stability have grown in response to studies indicating long term problems with "piping" and erosion. Leaks have been reported after several heavy rain events. Proposed solutions to the dike's problems have included the construction of a seepage berm on the landward side of the dike, with the first stage costing approximately $67 million (US$).
