Southwest Monsoon, localized thunderstorms to bring rains

The Southwest Monsoon (Habagat) and localized thunderstorms will bring rains over several areas on Sunday, PAGASA said.

The weather bureau said the Southwest Monsoon is affecting the western section of Southern Luzon.

Palawan will have cloudy skies with scattered rains and thunderstorms due to the monsoon. Moderate to at times heavy rains may possibly result in flash floods or landslides.

Metro Manila and the rest of the country meanwhile may experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized thunderstorms. During severe thunderstorms, flash floods or landslides may result.

Coastal waters will be moderate in the western sections of Northern and Central Luzon, and the northern section of Luzon.

Southern Luzon and the rest of the country will have slight to moderate coastal waters.

Sunrise was at 5:46 a.m. while sunset will be at 5:43 p.m.

PAGASA also said it is monitoring two weather disturbances outside the Philippine Area of Responsibility (PAR).

Severe Tropical Storm Matmo, which was formerly #PaoloPH, intensified into a typhoon and is still being monitored outside the Philippine Area of Responsibility (PAR) as of 8:00 PM today, October 4, 2025.

Typhoon Matmo, which was known as Paolo when it was inside PAR, was estimated to be located at 3 a.m. Sunday at 930 km west of Extreme Northern Luzon. Paolo exited PAR on Saturday morning.

Matmo has maximum sustained winds of 140 km/h near the center and with gustiness of up to 170 km/h. It is moving west northwestward at 25 km/h.

Meanwhile, Tropical Storm Halong was estimated at 3 a.m. to be at 2,190 km east northeast of Extreme Northern Luzon, packing maximum sustained winds of 65 km/h near the center and with gustiness of up to 80 km/h.

Halong is moving westward at 10 km/h.

"Sa ngayon nga, base sa pinakahuling datos natin, posibleng pa rin itong pumasok ito ng Philippine Area of Responsibility, pero most probably sa may northeastern boundary lang ito ng PAR," DOST-PAGASA weather specialist Obet Badrina said during a public weather forecast.

(For now, based on the latest data we have, it may possibly enter the Philippine Area of Responsibility but most probably in the northeastern boundary.)

"Hindi natin ito nakikitang makakaapekto sa ating bansa (We don't foresee it affecting our country)," he added.

The next tropical cyclone that will enter or be formed inside PAR will be named Quedan, Badrina said. —KG, GMA Integrated News
