North Indian Ocean cyclone seasons 2003, 2004, 2005, 2006, 2007

The 2005 North Indian Ocean cyclone season has no bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.

The scope of this basin is limited to north of the Equator and west of the Malay peninsula. The IMD and JTWC monitor this basin. The Arabian Sea and Bay of Bengal make up this basin, abbreviated ARB and BOB, respectively.

Season summary

In 2005, a total of twelve cyclonic disturbances were identified in North Indian Ocean, against a normal of fifteen. However, it was highest after 1992. Four of them became cyclonic storm in Bay of Bengal and were named, against a normal of five to six.

Storms

Tropical Depression 01B

Tropical depression (SSHS)
Duration	January 7 – January 10
Intensity	55 km/h (35 mph) (1-min),  1000 mbar (hPa)

In the second week of January, an area of convection persisted southeast of Sri Lanka. It organized into a tropical depression on January 8, but dissipated on the 10th due to vertical shear.

Cyclonic Storm Hibaru

Cyclonic storm (IMD)
Tropical storm (SSHS)
Duration	January 13 – January 17
Intensity	65 km/h (40 mph) (3-min),  1000 mbar (hPa)

Just behind the previous storm, a trough of low pressure developed into a tropical depression on January 13. Located a few hundred miles east-southeast of Sri Lanka, it meandered to the west, becoming a Cyclonic Storm on the 15th. Like its predecessor, Hibaru dissipated southeast of Sri Lanka on the 17th. This is the first season with two systems forming in January. The formation of a cyclonic storm in the month of January over low latitude is very rare; the last such occurrence was in the year 1987 (30 Jan. – 4 Feb, over the Bay of Bengal).

Depression ARB 01

Depression BOB 02

Depression (IMD)
Duration	June 27 – July 5
Intensity	45 km/h (30 mph) (3-min),  990 mbar (hPa)

Deep Depression BOB 03

Deep depression (IMD)
Duration	July 29 – July 31
Intensity	55 km/h (35 mph) (3-min),  988 mbar (hPa)

Torrential rains from the depression, and possibly other monsoonal storms, caused significant flooding in India which resulted in 1,044 fatalities.

Depression BOB 04

Tropical depression (SSHS)
Duration	September 12 – September 16
Intensity	45 km/h (30 mph) (1-min),  992 mbar (hPa)

Cyclonic Storm Pyarr

Cyclonic storm (IMD)
Duration	September 17 – September 21

An area of convection developed in the South China Sea on September 12. It moved west-northwestward, moving inland over Thailand on the 13th. It reached the Bay of Bengal on the 15th, and slowly developed. On September 17 it was upgraded to a tropical depression by the Indian Meteorological Department (but not by the JTWC), and on September 18 it became Cyclonic Storm Pyarr. The next day Pyarr made landfall, and on September 22 it dissipated over northwestern India.

Tropical Storm 03B

Tropical storm (SSHS)

Intensity	65 km/h (40 mph) (1-min),  994 mbar (hPa)

Deep Depression BOB 05

Deep depression (IMD)
Tropical storm (SSHS)
Duration	October 26 – October 29
Intensity	55 km/h (35 mph) (3-min),  998 mbar (hPa)

Tropical Storm 4B hit southeastern India on October 28 and dissipated the next day. Pakistan named this storm Baaz, the next name on the list, but the RSMC (New Delhi) did not upgrade it.

Heavy rains from the storm caused significant flooding in India. At least 100 people were killed, 50,000 were evacuated, and over 100,000 others were affected.

Cyclonic Storm Baaz

Cyclonic storm (IMD)
Tropical storm (SSHS)
Duration	November 28 – December 2
Intensity	85 km/h (50 mph) (3-min),  998 mbar (hPa)

The Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert early on November 27 on a low pressure system with persistent convection around its center not far from the Andaman Islands in the Bay of Bengal. At 2100Z that same day, about 100 n mi west of Port Blair, the JTWC upgraded the low pressure to a tropical depression, with the Indian Meteorological Department following suit the next day. It was upgraded into a tropical storm on the JTWC's following advisory at 0900Z on November 28. On November 28, the official RSMC in New Delhi upgraded the tropical storm to Baaz. The storm eventually dissipated as a significant tropical cyclone over sea near or north of Chennai. Baaz refers to the Saker Falcon in Arabic.

Cyclonic Storm Fanoos

Severe cyclonic storm (IMD)
Category 1 tropical cyclone (SSHS)
Duration	December 6 – December 10
Intensity	95 km/h (60 mph) (3-min),  998 mbar (hPa)

Tropical Storm 06B formed 550 nautical miles (1,020 km) east of Chennai on December 6, west of the Andaman Islands. It became Cyclonic Storm Fanoos on December 7. However, Fanoos weakened into a deep depression prior to crossing north Tamil Nadu coast near Vedaranyam at 0530 UTC (1100 IST) December 10. Fanoos weakened further into a low pressure area over south Tamil Nadu coast next day. Its remnants entered Arabian Sea but regeneration did not occur. Fanoos means chandelier in Urdu.

Severe damage was reported in Sri Lanka where thousands of homes were either damaged or destroyed. Due to the quick weakening prior to landfall, only minor damage occurred in Tamil Nadu. However, heavy rains forced the evacuation of 30,000 residents in the area. No fatalities were reported from Fanoos.

Deep Depression BOB 09

Deep depression (IMD)
Tropical storm (SSHS)
Duration	December 15 – December 22

A depression formed over Southeast Bay of Bengal on December 15. On December 17 it was recognised by the JTWC when it was 220-nautical-mile (410 km) east of Colombo, Sri Lanka. The system weakened into an area of low pressure over water on December 22.
