As dawn breaks on April 22, 2024, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) issues a comprehensive weather forecast for various regions across the archipelago. At 4:00 AM, meteorologists provide insights into the prevailing weather conditions, potential impacts, and coastal water conditions to aid individuals and communities in preparing for the day ahead.
Synoptic Overview:
A trough of Low Pressure Area (LPA) looms over southern Mindanao, while a Ridge of High Pressure Area extends over the eastern section of Northern Luzon. These atmospheric features dictate the weather patterns across different parts of the Philippines.
Forecast Weather Conditions:
- Basilan, Sulu, and Tawi-Tawi:
- Weather Condition: Expect cloudy skies with scattered rainshowers and thunderstorms, attributed to the trough of LPA.
- Impacts: There’s a risk of flash floods or landslides due to moderate to heavy rainfall.
- Metro Manila and the Rest of the Country:
- Weather Condition: Anticipate partly cloudy to cloudy skies with isolated rainshowers or thunderstorms, primarily caused by localized thunderstorms.
- Impacts: Severe thunderstorms may trigger flash floods or landslides, so caution is advised.
Forecast Wind and Coastal Water Conditions:
- Eastern Section of Northern Luzon:
- Wind Speed: Light to moderate, blowing from the east to southeast.
- Coastal Waters: Expect slight to moderate conditions with waves ranging from 0.6 to 2.1 meters.
Additional Insights:
- Regional Conditions: Parts of the Bicol region, Northern Samar, Oriental Mindoro, Marinduque, and Romblon will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms. Light to moderate winds from the east will prevail, accompanied by slight to moderate seas.
- LPA Outside PAR: A low-pressure area located outside the Philippine area of responsibility (PAR) is projected to bring rainfall over Mindanao. PAGASA assures that while it’s unlikely to develop into a typhoon, its trough will affect weather conditions in the region.
- High Temperatures in Luzon: Luzon, including Metro Manila, will endure elevated temperatures, with Tuguegarao possibly reaching 38 degrees Celsius. The heat is expected to persist for the next few days, prompting cautionary measures against heat-related illnesses.
- Extreme Heat Index: On a recent day, Aparri in Cagayan, Guiuan in Eastern Samar, and Roxas City in Capiz recorded scorching temperatures with a heat index peaking at 45 degrees Celsius.
