http://en.wikipedia.org/wiki/Cyclone_Bijli

Cyclone Bijli (JTWC designation: 01B, also known as Cyclonic Storm Bijli), was the first tropical cyclone to form during the 2009 North Indian Ocean cyclone season. Cyclonic Storm Bijli formed from an area of Low Pressure on April 14. Later that evening, RSMC New Delhi upgraded the Low Pressure into a Deep Depression. Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert and designated Bijli as Tropical Depression 01B. While RSMC New Delhi designated it as Deep Depression, during the morning on April 15. Later that day, both RSMC New Delhi and Joint Typhoon Warning Center issued full warnings on Bijli as it intensifies to a Tropical storm. They also classified Bijli as a Tropical cyclone on that day. But on the morning of April 17, RSMC New Delhi downgraded cyclone Bijli into a deep depression Due to land interaction. However, on April 18, RSMC New Delhi continues to issue warnings on Bijli as it moves toward Northern Myanmar (Burma). The word Bijli refers to lightning in Hindi.

Cyclone Bijli on April 16

On April 13, an area of shower and thunderstorms became slightly organized over the central Bay of Bengal.[1] Later that day, an area of low pressure developed underneath the convection as the system developed. Weak banding features also formed around the periphery of the storm.[2] By April 14, deep convection persisted around the center of circulation;[3] following the development the RSMC in New Delhi, India designated the system as Depression BOB 01.[4] Following further development, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA) as they anticipated the system to develop into a tropical storm.[5] Early the next morning the JTWC reported that the depression had intensified into a tropical storm and designated it as Cyclone 01B. The storm tracked towards the west-northwest due to a mid-level ridge over India.[6] Later that morning RSMC New Delhi reported that the depression had intensified into a deep depression and reported it was expected to intensify into Cyclonic Storm Bijli.[7] Around 1500 UTC, the RSMC New Delhi upgraded the system to a cyclonic storm and gave it the name Bijli.[8] Partial convective banding developed around the periphery of the system as it intensified.[9] The conditions for good outflow were present but did not develop. Around this time, the forward motion of the storm also slowed.[10] On April 16, the storm turned towards the northeast, paralleling the eastern coast of India.[11] Around 0600 UTC, RSMC New Delhi reported that Bijli had reached its peak intensity with winds of 75 km/h (45 mph 3-minute winds).[12] Early on April 17, RSMC New Delhi reported that Bijli had weakened into a deep depression as it started to move the northeast.[13]

Preparations, impact and aftermath

India

All four ports in Orissa were placed on high alert due to rough seas produced by the storm. A Local Cautionary Signal Number Three was issued for the Gopalpur, Puri, Paradeep and Chandabali ports.[14] Heavy rain from thunderstorms fell in coastal Andhra and Orissa due to the outer bands of Bijli.[15] Winds up to 55 km/h (35 mph) were also reported along the coast.[16]

Bangladesh

In Bangladesh, at least 40,000 volunteers from the Bangladeshi Red Cross were placed on standby in case evacuations were required.[17] Bangladeshi officials urged all ports to be on high alert and all fishermen to stay at port. The warning signal was placed at No. 3 on a scale of 1 to 10, with 10 being the highest level of warning.[18] Thousands of residents on Moheshkhali Island evacuated to 80 shelters.[19] As the storm neared landfall, ports in Chittagong raised their warning level to seven.[20] Following the increased warning level, an estimated 10,000 evacuated from coastal regions.[21][22] Weather officials estimated that the storm would produce a storm surge of 2.1 to 3 m (7 to 10 ft).[20] On April 17, all flights in and out of Bangladesh were cancelled due to dangerous conditions. Shelters were also opened and were reportedly able to accommodate about one million people.[23] In Chittagong, 6,000 volunteers set up to assist in the aftermath of the storm and about 283 medical teams formed within the group.[24] An estimated 200,000 people evacuated from Chittagong and the Cox’s Bazar District before the storm made landfall.[25]

The Tropical Rainfall Measuring Mission satellite, jointly operated by NASA and JAXA, estimated that Bijli produced a maximum of 129 mm (5.07 in) of rain over coastal Bangladesh, with rainfall rates reaching nearly 50 mm/h (2 in/h).[26] High winds downed several trees; numerous homes sustained damage and several ships on offshore islands were reportedly caught in the storm. High winds and heavy rains have also knocked out power to some communities.[22] A storm surge of 2.1 m (7 ft) was recorded in the Cox’s Bazar District with reports higher amounts in localized areas. At least 12 huts, 50 betel beef fields, and a large amount of salt have been damaged by the storm.[27] Later reports indicated that thousands of homes have been damaged or destroyed by the storm. The first fatality caused by Bijli occurred when a tree knocked down by high winds fell on a 9-year-old boy, killing him on impact and injuring his sister.[28] In the Cox’s Bazar District, a school teacher and two students were killed. One of the two children was trampled to death during the evacuation. The other child was killed when his home collapsed on top of him.[29]
