TD KONG-REY (NANDO) Update #001


for Monday, 26 August 2013 [7:42 PM PhT]


Issued: 6:00 PM PhT (10:00 GMT) Monday 26 August 2013
Next Update: 6:00 AM PhT (22:00 GMT) Tuesday 27 August 2013

The strong and broad Tropical Disturbance (LPA 91W) [NANDO] over the Central Philippine Sea, east of Aurora has reached Tropical Depression threshold this morning...and is now internationally known as KONG-REY - named after a mountain in Cambodia/a pretty girl in Khmer legend. This system has been moving towards the Batanes-Taiwan Area and will once again induce the Southwest Monsoon across the western sections of Luzon and Visayas.

This depression will induce the Southwest Monsoon (Hanging Habagat) - bringing cloudy and windy conditions with "on-and-off" slight to moderate to sometimes heavy rains across the western sections of Luzon & Visayas including Bicol Region...becoming more frequent along MiMaRoPa, CaLaBaRZon, Bataan and Metro Manila tonight and Tuesday. The threat of Flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes of the affected areas.

Residents and visitors along Extreme Northern Luzon, Taiwan, Yaeyama-Miyako Islands, and Okinawa-Ryukyu Islands should closely monitor the development of Kong-Rey (Nando).
