‘Maysak’ is the third most intense super typhoon to form early in the season (from January to April), a rare early super typhoon. The other two super typhoons with similar strength were: supertyphoon Ophelia in January 1958 and super typhoon Mitag in March 2002.
In the Philippines, only seven tropical storms or typhoons have hit Luzon between January and April since 1945, an average of one storm every ten years.
‘Maysak’ first developed into a tropical storm on Friday, March 26 across Micronesia, southeast of Guam. It slammed the island of Chuuk last weekend with damaging winds and torrential rainfall. Accuweather reported that more than 250mm or 10 inches of rain fell in under six hours over the island resulting to five casualties.
It passed the state of Yap in the Pacific islands with maximum winds of 230kph and gusts of up to 280kph.
On March 31, it strengthened into a super typhoon, reaching Category 5 hurricane status on the Saffir-Simpson Wind Scale. At its peak, ‘Maysak’ packed the strongest winds of 258kph and gusts of 280kph.
It was forecasted to weaken as it approaches the Philippines. ‘Maysak’ was given the local name ‘Chedeng’ as it entered PAR on April 1. Based on PAGASA’s severe weather bulletins, it showed a weakening trend:
