🍂🥵CRITICAL DROUGHT WATCH: EVEN SMALL POCKETS OF EXTREME DRYNESS PUT OVER 30 PROVINCES ON HIGH ALERT
According to soil moisture and drought intensity data from CzechGlobe via Windy, drought conditions remain a serious concern across parts of Luzon, Visayas, and Mindanao.
Following strict monitoring guidelines, any province showing even a small localized area of dark red/maroon shading is categorized under Exceptional to Extreme Drought based on its peak severity.
AFFECTED PROVINCES BY DROUGHT CATEGORY
🔴 EXCEPTIONAL TO EXTREME (Red to Dark Red / Maroon)
▪️ MINDANAO: Agusan del Norte, Basilan, Bukidnon, Cotabato, Davao del Sur, Davao Occidental, Davao Oriental, Lanao del Norte, Lanao del Sur, Maguindanao del Norte, Maguindanao del Sur, Misamis Occidental, Misamis Oriental, Sarangani, South Cotabato, Sultan Kudarat, Surigao del Norte, Zamboanga City, Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay
▪️ VISAYAS: Bohol, Capiz, Cebu, Eastern Samar, Iloilo, Leyte, Negros Occidental, Negros Oriental, Northern Samar, Samar, Southern Leyte
▪️ LUZON: Catanduanes, Masbate, Palawan, Romblon
🟠 MODERATE TO SEVERE (Orange to Dark Orange)
▪️ MINDANAO: Agusan del Sur, Davao de Oro, Davao del 55_, Sulu, Surigao del Sur
▪️ VISAYAS: Aklan, Antique, Biliran, Guimaras
▪️ LUZON: Albay, Aurora, Batangas, Camarines Norte, Camarines Sur, Cavite, Isabela, Laguna, Marinduque, Nueva Vizcaya, Occidental Mindoro, Oriental Mindoro, Quezon, Quirino, Rizal, Sorsogon
🟡 MINOR TO MILD (Yellow to Light Orange / Gold)
▪️ MINDANAO: Dinagat Islands, Tawi-Tawi
▪️ VISAYAS: Siquijor
UNDERSTANDING THE DROUGHT LEGEND
▪️ Exceptional to Extreme (Red / Dark Red / Maroon): Severe subsoil dryness in the 0–40 cm depth root zone. Groundwater reserves and deep root moisture are heavily depleted, posing major threats to agricultural production, crop yields, and local water supplies.
▪️ Moderate to Severe (Orange / Dark Orange): Significant reduction in subsoil moisture levels. This level directly affects regular crop growth, lowers streamflow discharge, and creates notable stress on irrigation infrastructure.
▪️ Minor to Mild (Yellow / Light Orange / Gold): Early-stage moisture deficit. Topsoil dryness is present but currently has minimal impact on regional agriculture.
WHY ARE PROVINCES UNDER DROUGHT ADVISORY EVEN IF IT IS RAINING OR DURING MONSOON SEASON?
▪️ Deep Subsoil Moisture vs. Rain Events: Drought intensity models measure accumulated moisture deep below the surface (0–40 cm root zone depth) over long periods, not short-term surface rain showers or localized thunderstorms.
▪️ Surface Runoff vs. Deep Absorption: Heavy monsoon downpours or sudden localized thunderstorms frequently result in fast surface runoff into drainage networks and ocean outlets without lingering long enough to infiltrate deep subsoils.
▪️ Extended Water Recovery Time: A single day of rain or short-lived rainfall surge does not immediately reverse a multi-month moisture deficit. Fully restoring dried subsoils and underground water tables requires weeks of consistent, long-term precipitation.
