MANILA, Philippines — Tropical Storm “Sinlaku” has intensified further while remaining outside the Philippine Area of Responsibility (PAR), as a high-pressure area continues to bring hot and humid conditions across the country on Friday, April 10, 2026, according to the state weather bureau PAGASA.

In its latest bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the storm was last located approximately 2,730 kilometers east of northeastern Mindanao. It is packing maximum sustained winds of 75 kilometers per hour and gusts of up to 90 kph while moving westward at 10 kph.
“It intensified further last night at around 8 p.m. and has reached tropical storm category, but it is not yet affecting the country,” PAGASA weather specialist Leanne Loreto said during the agency’s weather briefing.
PAGASA added that the weather system may enter the PAR between Wednesday and Thursday next week, where it will be given the local name “Caloy.” However, the bureau emphasized that the storm is unlikely to directly affect the country or make landfall.
Note: Tropical cyclones entering the PAR during summer are not uncommon, with recent examples including Super Typhoon Surigae (Bising) in April 2021 and Tropical Storm Aere (Dante) in May 2022. These cases show that early-year or summer cyclones can still develop or enter PAR despite being outside the peak typhoon season.
Meanwhile, a ridge of high pressure area (HPA) continues to dominate weather conditions over Northern and Central Luzon, bringing generally fair skies.
In Metro Manila and the rest of the country, residents can expect hot and humid conditions with partly cloudy to cloudy skies prevailing throughout the day.
PAGASA also warned of dangerous heat levels in some areas, with heat index values forecast to reach between 42°C and 51°C, classified as “danger level.”
The heat index refers to the temperature felt by the human body, combining air temperature and humidity, and is often higher than the actual air temperature.
