|At 4:00 p.m. today, Tropical Depression "JUANING" was estimated based on radar, satellite and surface data at 50 km Northeast of Daet, Camarines Norte (14.4°N 123.4°E) with maximum sustained winds of 75 kph near the center and gustiness of up to 90 kph. It is forecast to move West Northwest at 15 kph.
MANILA, Philippines (2nd UPDATE) - Metro Manila and 21 other areas in Luzon have been placed under public storm warning signal number 2 because of tropical storm "Juaning," weather bureau PAGASA said Tuesday afternoon.
As of posting time, these areas were also under signal number 2:
Meanwhile, signal number 1 was hoisted over the following areas:
Juaning was expected to make landfall over Polillo Island City by midnight or early Wednesday and will traverse Central Luzon, bringing heavy rains and strong winds.
PAGASA said heavy rainfall is expected to hit southern Luzon, including Laguna, Batangas, Cavite and the Bicol Region Tuesday night.
Metro Manila will be also be affected by the strong rains.
Central Luzon and Mindoro should also expect heavy rainfall on Wednesday morning.
Department of Science and Technology Graciano Yumul said while Juaning will not dump “Ondoy-like” rainfall, floods are likely to occur because of its duration.
“Ondoy brought 56 millimeters (mm) of rain per hour. Juaning brings 25 millimeters of rain per hour, so that’s just 40% compared to Ondoy. Pero ang difference, si Juaning mas matagal ang duration. Mas konti man ang dala niyang ulan, mas matagal naman. Kaya malaki pa din ang posibilidad ng floods at landslides,” explained Yumul.
PAGASA added it is unlikely that storm signal number 3 will be raised because of the slim chance that Juaning will reach winds of more than 100 kilometers per hour since it is already near land.
According to PAGASA’s 6-hour rainfall data, heavy rainfall hit Virac (199 mm), Legaspi (118 mm), NAIA (61 mm), Sorsogon (58 mm) and Science Garden (52 mm).
Rain measuring more than 45 mm is considered heavy.
Status of dams
PAGASA is closely monitoring the status of dams, specifically Angat Dam located in Barangay San Lorenzo, Norzagaray, Bulacan.
Dr. Susan Espinueva, head of PAGASA’s hydrometeorological division, said the dam's water level is at 8.39 meters before overflow level.
Binga and Ambuklao dams are also being monitored.
PAGASA, in its latest weather bulletin, said Juaning had slightly intensified as it moves toward Quezon province.
The tropical storm, which was spotted 70 km north northwest of Daet, Camarines Norte as of 10 p.m. Tuesday, was threatening Southern and Central Luzon, the weather bureau said.
It had maximum winds of 85 kph near the center and gustiness of up to 100 kph, according to PAGASA.
Juaning was moving west northwest at 11 kph and was expected to be 50 kilometers south of Dagupan City by Wednesday afternoon.
"Residents in low lying and mountainous areas under signals #2 and # 1 are alerted against possible flashfloods and landslides. Likewise, those living in coastal areas are alerted against big waves or storm surges generated by this tropical cyclone," PAGASA said.
Juaning was also projected to enhance the southwest monsoon and bring widespread rains over the rest of Luzon and Western Visayas.
It was expected to leave the Philippine area of responsibility by 2 p.m. Thursday.
