Super or Violent Typhoon Haiyan (Bagyong Yolanda) continues to move closer towards Eastern Philippines. The eye of Haiyan was last located approximately 420km northwest of Palau or abou 630km east southeast of Surigao City. According to the Japan Meteorological Agency maximum sustained winds remain at 215kph with gusts of up to 305kph. STY Haiyan is moving west northwestward at 35kph.
PAGASA has now issued Public Storm Warning Signal #3 for some provinces in Leyte and Samar Islands. We are also expecting the agency to issue Signal #4 Warnings later this afternoon. For the complete list of provinces, please click HERE (PAGASA Website)

Even though Super Typhoon Haiyan is still roughly 12 hours away from landfall, we are already starting to see some light to moderate rains associated with the outer bands of the typhoon impacting parts of Visayas. Light to moderate, and sometimes heavy, rains are already being felt across Leyte, Cebu, Bohol, Samar, and parts of Northern Mindanao especially around Surigao. The radar image above shows clusters of moderate rains moving in from the east. We expect to see as much as 50mm of rain through the next 6 to 12 hours with heavy rainfall becoming more widespread later tonight.

48-Hour Rainfall Forecast
Aside from the very strong and potentially catastrophic winds that Typhoon Haiyan will be bringing across the Philippines, the threat of widespread heavy rains also exist in the region. Thankfully, Haiyan/Yolanda will be moving rather quickly so rainfall accumulations will be around 300mm or so in the worst areas. Still, flooding and landslides are likely in areas where they usually occur. Our map above details where we think the heaviest rains will fall. You can see that even parts of Southern Luzon (including Manila) and Northern Mindanao could see some rains. But the heaviest should be focused across Central Visayas particularly across Leyte, Samar, Bohol, Cebu, Negros, and Panay.
Please stay tuned and always heed the warnings of your local officials! Remember that we are not an official weather agency so please do not use our forecasts for life or death decisions.
