THE Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa)-Mactan advised the public to stay at home due to localized thunderstorm that is causing moderate rain showers with lightning and strong winds.
Engineer Alfredo Quiblat, Pagasa Mactan chief, said the bad weather condition being experienced in Cebu, Leyte and Negros Oriental is not an effect of Tropical Depression Isang, which entered the Philippine area of responsibility Thursday morning, August 19.
Quiblat said localized thunderstorms may occur anytime of the day.
Pagasa defines thunderstorm as a weather disturbance that produces thunder and lightning, aside from wind and rain.
“Thunderstorms occur locally, often as episodes of cyclones, and in common with squalls, are marked by abrupt variations in pressure, temperature, and wind,” it said.
Quiblat said the lifespan of a thunderstorm is only one to two hours.
He advised the public to take precautionary measures, such as avoid touching anything that is made of metal and turn off cellphones and other appliances when lightning occur.
"Di lang ta mag-expose sa atong kaugalingon, kung naa ta sa balay, take some precautionary measures pud. Do not touch anything that is made of metal kay pwede man makasulod ang lightning strike ang current niya sa imung balay, lalo naay conductor antenna, cellphones. Mas maayo i-off. Cellphone is a good catcher of lightning," Quiblat said.
He said Tropical Depression Isang, meanwhile, is moving toward Taiwan but it may deflect to the right, toward Japan, and may intensify the southwest monsoon (habagat). This will cause moderate to heavy rains in the next two to three days, he added.
As of 10 a.m. Thursday, Isang was spotted at 1,410 kilometers east of northern Luzon, with maximum sustained winds of 45 kilometers per hour (km/h) near the center and gusts of up to 55 km/h. It was moving northwestward at 25 km/h.
It was forecast to remain a tropical depression and may weaken into a low pressure area by August 23 or earlier, said Pagasa.
No Tropical Cyclone Wind Signal is currently in effect. (MVE/LMY)
