Cyclonic Storm Laila (JTWC designation: 01B) is the first tropical cyclone of the 2010 North Indian Ocean cyclone season. It is currently intensifying and tracking toward southeastern India.

Meteorological history

In the middle of May 2010, an area of convection, or thunderstorms, persisted about 865 miles (1400 km) south of the Indian city of Kolkata (formerly Calcutta) in the Bay of Bengal. It was initially disorganized, although satellite imagery indicated a mid-level circulation.[1] After a few days, the convection began consolidating around a developing low-level circulation, and rainbands became evident. With low amounts of wind shear in the region, the Joint Typhoon Warning Center (JTWC) assessed its chances of development as fair.[2] The official warning agency in the basin – the India Meteorological Department (IMD) – classified the system as Depression BOB 001 at 0900 UTC on May 17.[3] About three hours after the depression was first classified, the IMD upgraded the system to a deep depression, indicating sustained winds of at least 34 mph (55 km/h).[4]

Late on May 17, the JTWC classified the system as Tropical Cyclone 01B, based on further organization. By that time, it was located about 485 miles (780 km) east-southeast of Chennai, Tamil Nadu, and was moving westward due to its position southwest of the subtropical ridge.[5] The IMD upgraded the deep depression to Cyclonic Storm Laila early on May 18.[6] With further consolidation of the convection throughout the day, the JTWC noted that the storm "[appeared] to be rapidly intensifying", which is a term referring to a quick drop in barometric pressure that usually coincides with a sharp increase in winds. By late on May 18, an eye feature became evident on satellite imagery,[7] and at 0000 UTC on May 19, the JTWC assessed Laila as producing maximum sustained winds of 75 mph (120 km/h), the equivalent of a minimal hurricane.[8]

Current storm information

As of 8:30 a.m. IST (0300 UTC) May 19, Cyclone Laila is located near 13.5°N 82.0°E, about 115 mi (190 km) ENE of Chennai, India. Maximum sustained winds are 45 knots (50 mph, 85 km/h), with stronger gusts. Minimum central pressure is 990 mbar (hPa; 29.23 InHg), and the system is moving to the northwest.

Preparations and impact

Early in the duration of the cyclone, the IMD noted the potential for heavy rainfall and gusty winds along the coast of Andhra Pradesh. The agency advised fishermen to avoid being in open seas. Additionally, the agency contacted state governments in the region to warn of the storm's threat.[4] The weather office has stated that the cyclone will not have an effect on the monsoon season.
