Typhoon Pablo (international name Bopha), which devastated Mindanao and left hundreds of people dead or missing, has regained strength off Luzon, the UK Met Office warned Friday.
The UK's national weather service, which has been tracking the typhoon along with other foreign agencies, said the typhoon may threaten the Philippines again, particularly northern Luzon.
The UK Met Office's showed images and an animation on Twitter of the typhoon rapidly swirling and changing direction.
"Typhoon Bopha was the first tropical cyclone worldwide to make landfall with winds of category 5 strength on the Saffir-Simpson Hurricane Wind Scale since Typhoon Megi in 2010," it said.
It added that Pablo "was the most intense typhoon to strike the island of Mindanao on record."
In its latest advisory Friday, the US Navy and Air Force Joint Typhoon Watch Center (JTWC) echoed the UK Met Office's new assessment on Pablo.
The typhoon weakened when it hit Mindanao, the Visayas and Palawan but regained quickly regained strength when it reached the open waters of the West Philippine Sea and started feeding on warm moisture coming from the east.
"Animated multispectral satellite imagery shows a recent rapid increase in organization with the development of an 11 (nautical mile) eye," the JTWC said.
Based on one-minute average readings, the typhoon is now packing maximum sustained winds of 148 kilometers per hour, with gusts of up to 185kph, according to the Hawaii-based weather task force. "The current intensity has been increased to 80 knots based upon a rapid rise in congruent Dvorak estimates from all agencies now reporting 77 knots."
