06 March 2012 Western Pacific & Eastern Asia Weather Update

A deep 1000hpa area of low pressure is pushing across Japan today bringing heavy rainfall and the potentiol for flooding conditions to the country today. This comes in the wake of a surge of rainfall from the same system that struck Eastern China on Sunday and Monday. In many areas to the West of Taiwan over 50-60mm of rainfall was reported in a 24hr period leading to some localized flooding in the region. Good news is Tuesday there will be a break in this activity as the low races across the Japanese Isles. Even there though totals are already climbing near 100mm of rainfall in the past 24hrs as the Rainy season stationary front persistantly sparks precipation in the region.  The analysis below shows these series of Low pressures and where rainfall is currently occuring in detail across the westerlies today.

continuing to push the low along expect improving conditions across the westerlies by Thursday. Although this will be short lived as the next developing Low Pressure area fires up in China by the end of the week.

In the tropics the Trade winds continue to dominate the weather. A weak disturbance is set to continue to push over the Philippines on Tuesday bringing rainfall to localized areas across Luzon, Visayas and Mindanao today.  Check Pats update on the 5th for a more detailed forecast in the PI.

Philippines 3-Day Forecast | March 5, 2012

Isolated thunderstorms continue to affect parts of Eastern Visayas and Mindanao today. Thankfully, there haven’t been a lot of heavy rain reports and based on the nature of the precipitation, we are not expecting large amounts of rain from this. However, some thunderstorms can trigger minor flooding and landslides so do be wary of that potential. Overall, rain showers will mainly affect Visayas and Mindanao leaving Luzon mostly dry and warm. Temperatures continue to climb in many areas, particularly Manila where a high of 34.5C was recorded two days ago. Daytime highs in the mid 30s will continue throughout the week due to the lack of cloud cover. As for the south, rains should remain scattered and light although another surge of rain might come in by the latter part of the week, potentially affecting Mindanao.

We’ll have another update by Thursday, March 8.
