Tropical Update

Issued (0830 UTC) 430pm PhT 022213

We are currently watching former Tropical Depression Crising which was actually been upgraded to a Tropical Storm by the Japan Meteorological Agency. Farther to the west, continuous light to moderate rains are causing flooding in Manila, Philippines.

A surprising move by the JMA has resulted in the "resurrection" of former Tropical Depression Crising. The now classified Tropical Storm Shanshan is located in the South China Sea (approximately 660km south southeast of Ho Chi Minh) and is moving slowly towards the Malay Peninsula. Not even the Joint Typhoon Warning Center is watching this system anymore so it really is perplexing to see JMA warn on this.

Nevertheless, TS Shanshan, which is very weak and has a fully exposed low-level center, will likely bring scattered to widespread rains across parts of Southern Vietnam and the Malay Peninsula over the next 2 to 3 days. Amounts could range from 50 to 100mm so flooding is possible.

Meanwhile, light to moderate rains continue to fall across parts of the Philippines today. Overnight rains have caused flooding in Metro Manila forcing schools and even government offices to close. Some flights have also been cancelled due to the poor weather. As much as 100mm have been recorded so far in the Southern Luzon region and even parts of Visayas and Mindanao have seen scattered rains.

Rains in Central and Southern Luzon, which are caused by the converging winds, will likely continue for at least another 12 to 24 hours before gradually subsiding. Elsewhere in the country, we expect cloudy skies with occasional light rain showers. More wet weather is in store for the southern parts, however, due to the Inter Tropical Convergence Zone (ITCZ),
