Typhoon Uwan weakens, expected to exit PAR on Nov. 11

Typhoon Uwan has weakened and is expected to exit the Philippine area of responsibility by Tuesday, Nov. 11. 

As of 8 a.m. on Nov. 10, the center of the eye of Typhoon Uwan was seen over the coastal waters of Bacnotan, La Union, according to PAGASA’s weather bulletin. As of early Monday morning, it was no longer a super typhoon. 

Over the next 12 hours, Typhoon Uwan is forecast to continue to move northwestward to northward over the West Philippine Sea at 25 km/h with maximum sustained winds of 150 km/h near the center, gustiness up to 230 km/h, and central pressure of 955 hPa. 

Maximum sustained wind measurements indicate the highest wind speeds brought by a typhoon. Gustiness refers to the sudden, brief bursts of wind speed—normally lasting less than 20 seconds—that are significantly higher than the average sustained wind speed. Central pressure, measured in hectopascals (hPa), indicates the lowest atmospheric pressure at the center of the storm. Intense typhoons have lower pressure, while weaker typhoons have higher pressure. 

Once Typhoon Uwan exits PAR by early morning Tuesday, Nov. 11, it's expected to change direction—from northwestward to northward. 

However, according to the 8 a.m. DOST-PAGASA weather report, a high-pressure system may cause Typhoon Uwan to re-enter the Philippine area of responsibility by midnight of Wednesday, Nov. 12 or early morning Thursday, Nov. 13. It will then follow a northward-northeastward direction. 

With Typhoon Uwan having a diameter of about 1,500 km, its effect will still be widespread, but weakened. 

On Nov. 11, most of Luzon, Iloilo, and Guimaras will still have cloudy skies. 

On Nov. 12, expect gusty winds in Batanes, Babuyan Islands, Ilocos Norte, and Ilocos Sur.  

Typhoon Uwan is expected to exit PAR for the second time around Friday noon, Nov. 14.
