FOR: TROPICAL STORM " " (DUJUAN)
TROPICAL CYCLONE: WARNING
ISSUED AT 5:00 PM, 21 February 2021
(Valid for broadcast until the next bulletin to be issued at 8 PM today)
TROPICAL STORM "AURING" SLIGHTLY ACCELERATES WHILE MOVING NORTHWESTWARD TOWARDS EASTERN VISAYAS-CARAGA AREA.
Hazards affecting land areas:
Heavy Rainfall:
• Today through tomorrow morning: Moderate to heavy rains over Caraga, Eastern Visayas, Misamis Oriental, Bukidnon, Camiguin, Catanduanes, Albay, and Sorsogon. Light to moderate with at times heavy rains over Zamboanga Peninsula, MIMAROPA, Davao Oriental, Davao de Oro, Quezon, and the rest of Bicol Region, Visayas, and Northern Mindanao.
• Tomorrow morning through Tuesday morning: Moderate to heavy rains over Bicol Region, Marinduque, Northern Samar, Eastern Samar, and Samar. Light to moderate with at times heavy rains over the rest of Visayas, MIMAROPA, Quezon, Aurora, Isabela, and Cagayan.
• Under these conditions, scattered flooding (including flash floods) and rain-induced landslides are likely during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps. Adjacent or nearby areas may also experience flooding in the absence of such rainfall occurrence due to surface runoff or swelling of river channels. PAGASA Regional Services Divisions may issue local thunderstorm/rainfall advisories and heavy rainfall warnings while the Hydrometeorology Division and River Basin Flood Forecasting and Warning Centers may issue General Flood Advisories and Basin Flood Bulletins as appropriate.
Strong Winds:
• In the next 24 hours, the combined effects of the surge of the Northeast Monsoon and Tropical Storm “AURING” will bring gale-force winds in areas under Tropical Cyclone Wind Signal (TCWS) #2 and strong breeze to near-gale conditions with occasionally higher gusts over the areas where TCWS #1 is in effect, as well as over CALABARZON, MIMAROPA, Aurora, and the rest of Visayas and Bicol Region.
Hazards affecting coastal waters:
• In the next 24 hours, rough to very rough seas will be experienced over the seaboards of areas under TCWS (2.6 to 4.5 m) and the eastern seaboard of Luzon not under TCWS (2.6 to 4.5 m). Rough seas (2.5 to 4.0 m) will prevail over the southern seaboard of Luzon (including the eastern seaboard of Palawan), the remaining seaboards of Visayas, and the northern, eastern, and western seaboards of Mindanao that are not under any TCWS. Sea travel is risky for all types of sea vessels over these waters.
• Moderate to rough seas (1.2 to 3.0 m) will be experienced over the remaining seaboards of the country. Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.
Track and intensity outlook:
• Tropical Storm “AURING” is forecast to continue moving generally west-northwestward to northwestward in the next 48 hours. On the forecast track and its probability cone, this storm may initially make landfall over the Dinagat Islands-Eastern Samar (southern portion including Homonhon Island)-Leyte area tomorrow morning.
• "AURING" is forecast to maintain its strength in the next 12 hours. However, the likelihood of weakening into tropical depression before it makes landfall is not yet ruled out. After landfall, “AURING” is forecast to weaken considerably due to significant terrain interaction and the increasing wind shear, leading to deterioration into a remnant low within 48 hours, possibly sooner.
Location of eye/center At 4:00 PM today, the center of Tropical Storm "AURING" was estimated based on all available data at 355 km East of Surigao City, Surigao del Norte (9.4°N, 128.7°E).
Strength Maximum sustained winds of 65 km/h near the center and gustiness of up to 80 km/h.
Movement Moving Northwestward at 20 km/h.
