The Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) Saturday (June 2) said tropical storm “Ambo” was upgraded to severe tropical storm.
In an 11 a.m. update today, Pagasa said the center of “Ambo” was estimated based on satellite and surface data at 200 km East Northeast of Casiguran, Aurora.
The storm is moving with maximum sustained winds of 85 kph near the center and gustiness of up to 100 kph, moving North Northwest at 13 kph.
“Ambo” is expected to be at 240 km Northeast of Aparri, Cagayan by tomorrow morning. It will be at 350 km Northeast of Basco, Batanes by Monday morning. By Tuesday morning, it will be at 680 km Northeast of Basco, Batanes.
Residents living in low lying and mountainous areas under signal No. 1 are advised against possible flashfloods and landslides.
Pagasa said the estimated rainfall amount is from 15 – 25 mm per hour (heavy) within the 400 km diameter of the Tropical Storm.
“Ambo” is expected to enhance the Southwest Monsoon that will bring rains over Central and Southern Luzon and Visayas.
Fishing boats and other small seacrafts are advised not to venture out into the seaboards of Southern Luzon and Visayas and the eastern seaboard of Northern and Central Luzon due to the combined effect of TS “Ambo” and the Southwest Monsoon.
