Track of TS 02B

An area of convection crossed the Isthmus of Kra on 23 October and entered the Bay of Bengal from the Pacific Ocean. It slowly organized and the Joint Typhoon Warning Center issued a TCFA at 0330 UTC on 28 October.

The India Meteorological Department later upgraded the low pressure area to a Depression on the same day, when the storm was located about 550 km (340 mi) east-northeast of Trincomalee, Sri Lanka. The storm further intensified into a Deep Depression on 29 October, and JTWC upgraded the system to a Tropical Storm.

As of 1930 IST (0200 UTC), 29 October 2012, Deep Depression BOB 02 was located near latitude 9.0°N and longitude 82.5°E, about 130 km (80 mi) east-northeast of Trincomalee, Sri Lanka and 500 km (310 mi) south-southeast of Chennai, India. The storm is forecast to intensify into a Cyclonic Storm, initially move westwards and then northwestwards, and cross north Tamil Nadu and adjoining south Andhra Pradesh coast between Nagapattinam and Nellore by 1200 UTC of October 31, 2012. Maximum sustained 3-minute wind speeds are estimated at 30 knots (55 km/h). Minimum central pressure is estimated at 1000 hPa (mbar).

The storm brought torrential rains to Sri Lanka. The Puttalam – Mannar road has come under about a meter of water near Eluwankulama due to the overflowing of the Kala Oya river. A 27-year-old woman was killed when a sand rock fell on her house during heavy rains at Habaraduwa in Galle District, according to the police. Rail services were temporarily suspended when electricity lines fell on the railway track.

Track of TD 02E

As of 2 a.m. PDT (0900 UTC) May 21, Tropical Depression Two-E is located within 45 nautical miles of 9.4°N 100.1°W, about 520 mi (835 km) south of Acapulco, Mexico. Maximum sustained winds are 30 knots (35 mph, 55 km/h), with stronger gusts. Minimum central pressure is 1005 mbar (hPa; 29.68 InHg), and the system is moving west at 5 kt (6 mph, 9 km/h).

Tropical Cyclone Two (02A), located approximately 65 nm north-northeast of Cape Guardafui, Somalia, has tracked west-northwest-ward at 04 knots over the past six hours. Maximum significant wave height is 17 ft.

Animated water vapor imagery shows increased poleward outflow with the approach of a mid-latitude trough to the north. This event has deepened the convection associated with the system. The current position is based on animated multispectral imagery and extrapolated from microwave imagery.

The current intensity is based on a Dvorak estimate of T3.5. Upper level analysis indicates TC 02A is under the ridge axis in an area of moderate vertical wind shear (VWS). The system is expected to continue to track slowly to the west into the Gulf of Aden, steered by the mid-level subtropical ridge to the north.

As the aforementioned mid-latitude trough digs further south, an increase in VWS coupled with the entrainment of drier air from the Somali Desert and cooling sea surface temperatures of the gulf, TC 02A is expected to gradually weaken and dissipate as a significant tropical cyclone over water by TAU 72. The available numeric guidance is in overall agreement with this track forecast.
