MANILA (UPDATE)—Typhoon Tisoy slightly weakened early Tuesday after hitting land over Sorsogon province but it was still "powerful," state weather agency PAGASA said.
The eye of the typhoon was last seen in the coastal waters of San Francisco, Quezon as of 7 a.m., the agency said.
It was packing maximum sustained winds of 155 kilometers per hour (kph), with gusts of up to 235 kph.
"Hindi po puwedeng maging kampante ang ating mga kababayan dahil malakas pa rin at mapaminsala si bagyong Tisoy. Konti lang 'yong ibinawas ng strength niya but still it is a powerful typhoon," said PAGASA weather specialist Loriedin Dela Cruz.
PAGASA said Tisoy's eyewall, considered the most damaging part of the typhoon, was bringing violent winds and intense rains over Southern Quezon, Marinduque, and Romblon.
