MANILA (UPDATE) - Tropical cyclone warning signal no. 5 was lifted before noon Sunday after Typhoon Rolly, the world's strongest storm so far this year, weakened into a typhoon following two landfalls in Bicol region, the state weather bureau said.

But Siony remains less likely to affect the country over the next 2 to 3 days, the weather bureau added.

In its latest weather bulletin issued at 11 a.m., PAGASA said Rolly (international name: GONI) was packing strong maximum winds of 215 kilometers per hour near the center and gusts of up to 295 km per hour while moving west at 25 kph as of 10 a.m.
