|Current Status & Outlook||Super Typhoon BISING (SURIGAE) is now an extremely catastrophic category 5 system after rapidly intensifying over the past 12 hours, making it the most powerful typhoon ever formed in the month of April in the Western Pacific Ocean – since the start of the operational Dvorak Analysis in the 1980s. It has now 1-min. sustained winds of 305 km/hr (based on the JTWC data).
This typhoon is expected to bring occasional rains with severe thunderstorms and gusty winds across Samar and Bicol Provinces today and tomorrow.
24-hr Outlook: STY BISING (SURIGAE) is forecast to pass well to the east of Catanduanes, more or less 220 km away from the island province by 2:00 AM early tomorrow morning. It is expected to move west-northwestward across the western portion of the Central Philippine Sea at a decreased forward speed of 11 km/hr. This cyclone will therefore weaken to minimal Super Typhoon strength within the next 12 to 24 hours as it undergoes an Eyewall Replacement Cycle (ERC).
