At least 17 provinces in Mindanao will experience dry spell while 11 provinces will be hit by drought by end of April 2019, according to a report of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
In a March 22 report released on Monday, Pagasa said the dry spell will hit Bukidnon, Camiguin, Lanao del Norte, Misamis Oriental, Compostela Valley, Davao City, Davao del Norte, Davao del Sur, Davao Occidental, Davao Oriental, North Cotabato, Sarangani, Agusan Del Norte, Agusan del Sur, Surigao del Sur, Basilan and Lanao del Sur.
A drought will occur in Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, Misamis Occidental, South Cotabato, Sultan Kudarat, Dinagat Islands, Surigao del Norte, Maguindanao, Sulu and Tawi-Tawi.
Mindanao provinces will experience normal rainfall condition next month. Except for Misamis Occidental and Dinagat Island provinces, the island’s regions will receive near normal rainfall by May.
According to Pagasa weather specialist Bema Tajones, dry spell means three consecutive months of below normal rainfall and 21% to 60% reduction from the average or two consecutive months of way below normal rainfall with more than 60% average reduction from the average rainfall.
She said drought happens when an area experiences three consecutive months of way below normal rainfall with greater than 60% reduction from the average rainfall or five consecutive months of below normal rainfall with 21% to 60% reduction from the average rainfall.
By end of May, Pagasa said only the provinces of Misamis Occidental and Dinagat Islands in Mindanao will experience drought.
Conditions in all provinces of Mindanao are expected to normalize beginning end of June although other provinces in the island will continue to experience drought during that month, as the “weak or even moderate strength” El Niño is forecast to continue until October before it will weaken in the last quarter of this year, according to Pagasa.
