LPA over Visayas may dissipate in 24 hours - Pagasa-A A +A
Wednesday, April 16, 2014
THE low pressure area (LPA) lingering inside the country for almost two weeks now is expected to dissipate in the next 24 hours, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) on Wednesday.
Pagasa weather forecaster Jun Galang said that the LPA is expected to dissipate because it is expected to hit land in some areas in the Visayas.
He added that the LPA has an erratic movement as it continues to move “very slowly” because of the presence of a ridge of high pressure area (HPA) over Luzon that prevents the LPA from moving freely.
Galang said if the LPA does not dissipate, it will likely exit the country via West Philippine Sea on Good Friday.
Galang said a gradual weather improvement is expected in the Visayas in the next two days.
He noted that the LPA is still in the sea and has a “slim chance” of re-intensifying into a tropical cyclone due to a strong vertical wind shear or winds from different directions that blow into the country, which continue to interact with its circulation.
As of 4 a.m., the LPA was spotted some 120 kilometers (km) east of Hinatuan, Surigao del Sur (8.5ºN, 127.0ºE).
For Wednesday forecast, the Visayas will have cloudy skies with moderate to occasionally heavy rains which may trigger flashfloods and landslides.
He advised residents of these areas to be prepared and closely monitor the weather situation.
He added that the LPA will also affect Bicol and Caraga regions and the Mindoro, Marinduque, Romblon and Misamis Oriental inducing cloudy skies with scattered light to moderate rains in these regions.
Pagasa issued a rainfall advisory at 6:35 a.m. due to trough of LPA as moderate to occasionally heavy rains affecting portions of Biliran, Northern Samar, Samar and Eastern Samar which may continue for two- three hours.
It added that intermittent light to moderate rains over portions of Western Visayas, Central Visayas and the rest of Eastern Visayas which may prevail for two- three hours.
The public and the Disaster Risk Reduction and Management Council concerned are advised to monitor the weather condition and watch for the next advisory to be issued. (PNA)
