Severe Tropical Storm (STS) Leon has intensified; should it continue to do so, it may develop into a typhoon in the next 12 hours, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported.
“There is an increasing chance that Leon will reach the super typhoon category during its period of closest approach to Batanes,” the weather bureau stated. It also said landfall in Batanes is possible.
Close to its center, the STS already generates maximum sustained winds of 110 kilometers per hour (kph), with a gustiness peaking at 135 kph. Typhoons produce maximum wind speeds of 118 to 184 kph, and super typhoons exceed the 185 kph mark.
At 4 AM, the cyclone was detected to be 645 km east of Tuguegarao City in Cagayan and moving west northwestward at 10 kph. Forecasts indicate its exit from the Philippine Area of Responsibility (PAR) on Friday.
