Tropical Storm Kristine strengthened early Tuesday, leading the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) to issue Tropical Cyclone Wind Signal No. 1 for 24 areas nationwide.
According to PAGASA's 5 a.m. cyclone bulletin, Kristine’s center was last observed 390 km east of Virac, Catanduanes. The storm has maximum sustained winds of 65 kph and gusts reaching up to 80 kph, moving westward at 15 kph.
PAGASA indicated that rapid intensification of the tropical cyclone remains possible as it is still over the Philippine Sea, with favorable environmental conditions supporting its development.
The state weather bureau stated that Kristine could strengthen into a severe tropical storm by Wednesday, October 23, and is expected to make landfall in Isabela by Wednesday evening.
PAGASA predicts that Kristine will move "northwestward to west-northwestward until Thursday, October 24, before shifting westward for the remainder of the forecast period." It is expected to exit the Philippine area of responsibility by Friday evening, October 25.
PAGASA added that Tropical Storm Kristine could intensify into a typhoon by Friday as it moves over the West Philippine Sea.
PAGASA stated that the highest possible Wind Signal that may be raised during Kristine's occurrence is Wind Signal No. 4, given the potential for rapid intensification.
