Template:Infobox indian current Cyclonic Storm Helen is a relatively weak tropical cyclone that formed in the Bay of Bengal Region on November 18, from the remnants of Tropical Storm Podul. It was classified as Deep Depression BOB 06 by the IMD on November 19. As it was moving on a very slow northwest direction on November 20, it became Cyclonic Storm Helen as it brought light to heavy rainfall in eastern India. It then became a Severe Cyclonic Storm on the afternoon hours of November 21.
Meteorological history
Tropical storm (39–73 mph, 63–118 km/h)
Category 1 (74–95 mph, 119–153 km/h)
Category 2 (96–110 mph, 154–177 km/h)
Category 3 (111–129 mph, 178–208 km/h)
Category 4 (130–156 mph, 209–251 km/h)
Category 5 (≥157 mph, ≥252 km/h)
Unknown
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionLate on November 17, the remnant energy of Tropical Storm Podul contributed to the development of a trough over the Bay of Bengal, located near the Andaman Islands. During the next couple of days, the storm slowly organized and consolidated, prompting the Joint Typhoon Warning Center (JTWC) to issue a Tropical cyclone formation alert (TCFA) during the early hours of November 19.[1] Later on the same day, the India Meteorological Depatment (IMD) upgraded the storm to a depression, classifying it as BOB 06,[2] followed by the JTWC reporting that the storm had reached Tropical Storm strength.[3] A couple of hours later, the IMD upgraded BOB 06 into a Deep Depression, as the storm continued to intensify.[4]
The storm slowly drifted west-northwestward, while deep convection consolidated around the system's well-defined center of circulation.[5] In the early hours of November 20, the IMD classified BOB 06 as a Cyclonic Storm, thereby officially naming it Helen.[6] Early on November 21, Helen continued to intensify into a Severe Cyclonic Storm, reaching its peak intensity of 100 km/h (62 mph) with a central pressure of 990 mbar (29 inHg).
Shortly before landfall, the storm's convection sheared to the north, causing its low level circulation to fully expose followed by the JTWC issuing its final bulletin, reporting that the storm had weakened due to land interaction.[7] Helen made landfall south of Machilipatnam, Andhra Pradesh and rapidly deteriorated into a deep depression.[8][9]
Current Storm Information
As of 1730 IST (1200 UTC), 22 November 2013, Deep Depression Helen crossed was located inland near latitude 15.9°N and longitude 80.7°E, 60 km/h (37 mph) southwest of Machilipatnam. The storm is forecasted to track west-southwestwards and weaken into a depresion in the next six hours. Maximum sustained 3-minute wind speeds are estimated at 55 km/h (34 mph), gusting to 65 km/h (40 mph). Minimum central pressure is estimated at 1,000 millibars (30 inHg).
Preparations and Impact
The Andhra Pradesh government alerted all coastal districts of the state, especially southern coastal districts. The district collectors were directed to evacuate people from low-lying areas near the coast.[10] More than 11,000 people were evacuated from the areas affected by the storm. Ten teams of the National Disaster Response Force were deployed for rescue operations in the affected areas. A total of seven deaths have been reported in incidents related to the cyclone.[11]
Three boats carrying 20 fishermen were reported missing, out of which two were reported to be safe and on their way back to the coast. Efforts are on to ensure the safety of the third. The Coast Guard's vessel Avantibai and a Chetak helicopter of the Navy have been dispatched for search and rescue of the missing fishermen.[11]
Helen brought extensive damage to Machilipatnam in Krishna district, with uprooted trees and electric lines. The districts of Krishna, East Godavari and Srikakulam, Visakhapatnam and Guntur suffered heavy rainfall. Heavy damage to harvest crops was also reported, with the West Godavari district being worst affected. Paddy, Coconut and Banana crops have suffered damage.[11]
