FROM TODAY UNTIL SUNDAY (23-25 MAY), THE INTERTROPICAL CONVERGENCE ZONE (ITCZ) WILL CONTINUE TO AFFECT MINDANAO, WESTERN VISAYAS, NEGROS ISLAND REGION, AND PALAWAN, PRODUCING CLOUDY SKIES WITH SCATTERED RAINS AND THUNDERSTORMS. ELSEWHERE, THE EASTERLIES WILL BRING PARTLY CLOUDY TO CLOUDY CONDITIONS, WITH ISOLATED THUNDERSTORMS THAT MAY GENERATE SHORT-DURATION HEAVY RAINFALL.

FROM MONDAY TO TUESDAY (26-27 MAY), AS THE ITCZ GRADUALLY WEAKENS, ITS RESIDUAL EFFECTS WILL STILL BRING CLOUDY SKIES WITH SCATTERED RAINS AND THUNDERSTORMS OVER PALAWAN, BASILAN, SULU, AND TAWI-TAWI. THE REST OF THE ARCHIPELAGO WILL EXPERIENCE PARTLY CLOUDY TO CLOUDY SKIES WITH ISOLATED RAINSHOWERS OR THUNDERSTORMS.

FROM WEDNESDAY TO FRIDAY (28-30 MAY), A FRONTAL SYSTEM ADVANCING FROM THE NORTH WILL BEGIN TO AFFECT EXTREME NORTHERN LUZON, WHILE SOUTHWESTERLY WINDFLOW BRINGS RAIN-BEARING CLOUDS TO ILOCOS REGION, BATAAN, AND ZAMBALES. THESE AREAS CAN EXPECT CLOUDY CONDITIONS WITH SCATTERED RAINS AND THUNDERSTORMS, WHILE THE REST OF THE COUNTRY MAINTAINS GENERALLY FAIR WEATHER WITH ISOLATED RAINSHOWERS OR THUNDERSTORMS.

A LOW PRESSURE AREA (LPA) EMBEDDED ALONG THE ITCZ MAY FORM WITHIN THE OUTLOOK PERIOD.

THIS WEATHER OUTLOOK WILL BE UPDATED IF THERE ARE SIGNIFICANT CHANGES IN THE FORECAST SCENARIO, THROUGH THE ISSUANCE OF 24-HOUR PUBLIC WEATHER FORECASTS AND WEATHER ADVISORIES.
