A rainy weekend is in store for parts of Luzon today as scattered rains and thunderstorms due to the easterlies move in. Some of these cells can bring heavy rainfall in short amount of time leading to potential flooding and even landslides. Meanwhile, the tropical disturbance that we've been watching--Invest 99W--continues to move westward and is now over the South China Sea (West Philippine Sea). This LPA did bring some rains over Visayas and Mindanao but fortunately, it didn't intensify into a strong cyclone (although JMA did briefly consider as a Tropical Depression).

Right now, scattered are affecting Northern and Southern Luzon including the Bicol Region. Some rains are also moving into parts of Central Luzon and may affect Metro Manila and surrounding areas over the next few hours. Parts of Eastern Visayas and Northern Mindanao could also see some rains tonight.
3-Day Forecast (NOT OFFICIAL!)
Rains will linger over Luzon through tomorrow, Sunday, while Visayas and Mindanao will have partly cloudy skies with small chance of rains especially in the afternoon. A frontal system is forecast to move in by Monday likely spawning more rains across the northern half of Luzon by Monday. Rain showers are expected to continue spreading southward into the Bicol Region and parts of Visayas. We also expect another round of showers to affect Mindanao, courtesy of the Easterlies, which could last into the early part of next week. We don't expect any tropical systems to form this week.
We'll have another update on Tuesday, March 26.
