Four provinces in Mindanao are now under public storm warning signal no. 1 as the low pressure area (LPA) east of Mindanao has intensified a into a tropical depression, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Friday.
In an interview, PAGASA weather forecaster Manny Mendoza said tropical depression “Caloy” is the third tropical cyclone to enter the country this year and the first for this month of March.
He said that as of 4:00 a.m., “Caloy” was spotted some 360 km east of Davao City (7.2ºN, 129.0ºe) with maximum sustained winds of 45 kph and forecast to move west slowly.
Citing numerical models and its slow movement, he said “Caloy” may make landfall in Davao Oriental likely within the next 24 hours.
PAGASA said that public storm warning signal no. 1 (Winds of 30-60 kph expected in at least 36 hours) was hoisted over Surigao del Sur, Agusan del Sur, Davao del Norte and Davao Oriental.
According to PAGASA, the potential impact of winds is the following:
•Twigs and branches of trees may be broken;
•Some banana plants may tilt or land flat on the ground;
•Rice in flowering stage may suffer significant damage;
•Some nipa and cogon houses may be partially unroofed; and
•Travel of small seacrafts and fishing boats is risky
PAGASA added that residents living in low-lying and mountainous areas under public storm warning Signal Number 1 are alerted against possible flashfloods and landslides.
He said estimated rainfall amount within the 300-km diameter of the cyclone is from five to 15 millimeters per hour, which is classified as “moderate to heavy.”
If “Caloy” maintains its slow westward track, he said the cyclone will likely traverse Mindanao and may linger inside the country.
Because of the tropical depression, Mendoza said most parts of the Visayas and Mindanao will experience “cloudy skies” with light to moderate rains until weekend.
He noted that the rest of Luzon including Metro Manila will not be affected by the cyclone and will continue to experience fair weather aside from isolated light rains due to the northeasterly windflow.
Meanwhile, PAGASA said the cyclone is projected to be at 180 km east of Davao City by Saturday morning.
By Sunday morning, it is expected to be at 40 km north of Davao City and at 180 km west of Davao City on Monday morning.
In its Friday forecast, PAGASA said the provinces of Surigao del Sur, Agusan del Sur, Davao del Norte and Davao Oriental will have rains with gusty winds with moderate to rough seas. Visayas and the rest of Mindanao will be cloudy with light to moderate rainshowers and isolated thunderstorms.
It added Metro Manila and the rest of Luzon will experience fair weather aside from isolated light rains while Western Visayas will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms.
PAGASA also said that moderate to strong winds from the east to northeast will prevail over Luzon and coming from the northeast to northwest over the rest of the country. The coastal waters throughout the archipelago will be moderate to rough.
The state weather bureau also issued gale warning as strong to gale force winds associated with the surge of northeasterly surface windflow will affect the northern seaboard of Northern Luzon and eastern seaboards of Northern and Central Luzon.
“Fishing boats and other small seacrafts are advised not to venture out into the sea while larger sea vessels are alerted against big waves,” it warned. PNA
