Typhoon Rolly (Goni) could become a super typhoon in the next 12 hours, warned the state weather bureau in its 11 pm bulletin on Friday, October 30.
The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) explained that Rolly "underwent extremely rapid intensification over the last 24 hours."
"Owing to very favorable conditions, there is an increasing likelihood that this typhoon will reach super typhoon category over the next 12 hours," PAGASA said, referring to the fact that Rolly remains over the Philippine Sea, and tropical cyclones strengthen over water.
As of Friday evening, Rolly now has maximum sustained winds of 215 km/h and gustiness of up to 265 km/h. If its maximum sustained winds exceed 220 km/h, it would be classified as a super typhoon.
