Typhoon Mawar is an intensifying tropical cyclone currently moving away from Guam. The second named storm and the first typhoon of the 2023 Pacific typhoon season, Mawar originated from an area of low-pressure south-southwest of Chuuk Lagoon that developed into a tropical depression on May 19. It fluctuated in intensity and became a tropical storm, after which it unexpectedly intensified into a Category 4-equivalent super typhoon on the Saffir–Simpson hurricane wind scale. Typhoon Mawar hit Guam as a Category 4 storm on May 24, bringing hurricane-force winds and heavy rain marking the strongest storm to hit the island in decades.[1][2]

On May 17, a weak low-level circulation (LLC) located 865 km (535 mi) south of Guam was marked by the Joint Typhoon Warning Center (JTWC) as Invest 97W. Global forecast models such as the Global Forecast System and Navy Global Environmental Model indicated that the disturbance would gradually intensify into a tropical cyclone in the upcoming days.[3] The atmospheric convection broadened over the LLC the following day.[4] Later the JTWC issued a Tropical Cyclone Formation Alert on the disturbance after thunderstorms became very wide and organization had improved.[5] The Japan Meteorological Agency also began tracking the system, marking it as a low-pressure area[6] shortly before upgrading it to a tropical depression on May 19.[7] The system steered northward due to the weak trade winds.[8] The JTWC followed suit on May 20 after the depression had strengthened from warm waters and poleward and westward outflow, designating it 02W.[9] The same day, the depression upgraded to a tropical storm after a scatterometer pass revealed winds of 65 km/h (40 mph) in the southwest quadrant, as it formed a central dense overcast.[10] The JMA in response, assigned the name Mawar to the storm.[11] The JMA further upgraded the storm to severe tropical storm status at 00:00 UTC of May 21,[12] as the deep convection in the CDO completely obscures the LLCC.[13] Both the JMA and JTWC upgraded Mawar to a typhoon on May 21.[14][15] An eye was forming under the CDO on May 22,[16] as rainbands wrapped around the circulation center of the system.[17]

On May 23, Mawar rapidly intensified to winds of 210 km/h (130 mph), equivalent to Category 4 strength on the Saffir–Simpson hurricane wind scale. Furthermore, Mawar underwent an eyewall replacement cycle.[18] The typhoon strengthened even further into a super typhoon, the highest classification of strength from the JTWC, after reaching winds of 250 km/h (155 mph).[19] The circulation center became cloud-filled as the system weakened from the cycle.[20] On May 24, the center of Mawar passed about north of the northern tip of Guam as a Category 4 typhoon, around 9 pm local time and slightly weakened.[21][22] However, that did not prevent the Extreme Wind Warning from issued by the National Weather Service in Guam for the northern half of the island, the first ever issuance by the WFO in record, after the NWS gave the WFO a green light to be able to issue EEWs in 2023.[23][24] On May 25, the aforementioned eyewall replacement cycle had been completed, and a uniform eye had appeared. Initially cloud-filled, the system quickly cleared it out and continued strengthening slowly as it moved west-northwestward.[25][26] On the same day, Mawar recorded total winds of 155 knots (285 km/h), in sustained winds of 1 minute, according to the JTWC reaching the status of super typhoon category 5. [27]

Current storm information

As of 12:00 UTC May 25, Typhoon Mawar is located near 14°48′N 141°36′E / 14.8°N 141.6°E / 14.8; 141.6 (Mawar) or about 191 nautical miles (355 km; 220 mi) west-northwest of Naval Base Guam. Maximum 10-minute sustained winds are at 110 knots (205 km/h; 125 mph), with gusts up to 155 knots (285 km/h; 180 mph), while maximum 1-minute sustained winds are at 150 knots (280 km/h; 175 mph). The minimum central barometric pressure is 910 hPa (26.87 inHg), and the system is moving west-northwest at 10 kn (19 km/h; 12 mph).

Preparations and impact

Mariana Islands

Typhoon Mawar approaching and making its closest pass of Guam on May 24

A typhoon watch was in effect for the Mariana Islands by May 21;[28][29] a flood watch was also issued for the islands as the storm neared.[30] Guam Governor Lou Leon Guerrero and Rear Admiral Benjamin Nicholson (commander of Joint Region Marianas) set the Condition of Readiness at level 3 (COR 3) on May 21 while Mawar was a tropical depression some 660 mi (1,060 km) south-southeast of Guam. Military installations on Guam began to secure facilities in response to the anticipated storm.[31] The United States Coast Guard evacuated two of its vessels stationed on the islands out to sea.[30] COR 2 was declared at 8 p.m. ChST later that day, prompting the closure of courts and public schools as the Government of Guam suspended nonessential services.[32][28] Hospitals and clinics on Guam also curtailed services in response to the COR 2 issuance.[33] Other neighboring islands, such as Rota and Saipan, also closed establishments in preparation for Mawar.[34][35] All public schools on the Northern Marianas Islands were closed beginning on May 22.[36] Flights to Guam were cancelled between May 22–24.[37] The SCLC caging playoffs were also suspended due to the incoming tempest.[38]

The last NEXRAD radar scans of Typhoon Mawar before the radar went out. The NEXRAD velocity (right side) had a max wind speed of 193 mph (311 km/h) about 400 feet (120 m) above the surface.

Guerrero declared a state of emergency for Guam on May 22, stating that Mawar presented an "imminent, credible and significant threat to the health, safety and welfare of Guam."[39] President Joe Biden approved emergency declarations for Guam and the Commonwealth of the Northern Mariana Islands the same day, enabling the allocation of federal resources to the threatened islands[40][41] COR 1 was placed in effect for Guam at 1 p.m. ChST on May 23.[42] Guerrero issued an evacuation order for the Guam's low-lying coastal districts, ordering residents to evacuate to higher ground by 6 p.m. ChST later that day.[43] Villages subject to the evacuation order included Hågat, Humåtak, Malesso, and Talo'fo'fo. The evacuation order also directed the Guam National Guard to assist evacuations.[44] The Guam Department of Education opened emergency shelters at 12 schools at 8 a.m. ChST on May 23.[45][44] By 9 p.m. ChST, 862 people were housed in government-operated shelters.[46] The evacuation of people on military installations in threatened areas was also authorized by Nicholson.[47]

Power outages began affecting parts of Guam on May 22 as winds from Mawar intensified.[48] Guam International Airport also recorded winds up to 104.7 miles per hour (168.5 km/h) as Mawar impacted the island.[49][50]

The Weather Prediction Center recorded that multiple locations in Guam received at least 20 inches (51 cm) of rain during Typhoon Mawar, with most of it falling in just three hours.[51] A United States Geological Survey rain gauge in Dededo, Guam measured the most rainfall at 28.42 inches (72.2 cm).[52]

Philippines

A total of 689,885 family food packages have been pre-positioned nationwide by the Department of Social Welfare and Development (DSWD) in preparation of possible landfall of Mawar. [53][54]
