SEVERE WEATHER BULLETIN #21
FOR: TROPICAL DEPRESSION "#AuringPH" (DUJUAN)
TROPICAL CYCLONE: WARNING
ISSUED AT 5:00 AM, 22 February 2021
(Valid for broadcast until the next bulletin to be issued at 8 AM today)
TROPICAL DEPRESSION "AURING" CONTINUES TO WEAKEN AS IT APPROACHES DINAGAT ISLANDS-HOMONHON ISLAND AREA.
Hazards affecting land areas:
Heavy Rainfall:
• Today: Moderate to heavy rains over Bicol Region, Northern Samar, Samar, Eastern Samar, Biliran, Leyte, Marinduque, Romblon, and Quezon. Light to moderate with at times heavy rains over Aurora and the rest of Visayas, MIMAROPA, and CALABARZON.
• Tomorrow: Light to moderate with at times heavy rains over CALABARZON, MIMAROPA, Metro Manila, Camarines Norte, Bulacan, Aurora, Isabela, Cagayan including Babuyan Islands, and Batanes.
• Under these conditions, isolated to scattered flooding (including flash floods) and rain-induced landslides are still likely during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps and in localities that received significant rainfall over the past couple of days. 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 Northeast Monsoon and “AURING” will bring strong breeze to near-gale conditions with occasionally higher gusts over the areas where Tropical Cyclone Wind Signal (TCWS) #1 is in effect, as well as over Aurora, Quezon, Marinduque, Romblon, Oriental Mindoro, Batanes, Babuyan Islands, the northern portions of Ilocos Norte and mainland Cagayan, Cuyo Islands, Cagayancillo Islands, and the rest of Visayas and Bicol Region.
Hazards affecting coastal waters:
• In the next 24 hours, rough seas will be experienced over the seaboards of areas under TCWS #1, the eastern seaboard of Central Luzon, the eastern seaboard of Southern Luzon not under any TCWS (2.5 to 3.5 m), the southern seaboard of Luzon and the remaining seaboards of Visayas (2.5 to 3.0 m). Sea travel is risky especially for those using small seacrafts.
• Moderate to rough seas (1.2 to 2.5 m) will be experienced over the remaining seaboards of Luzon, and the northern and western seaboards of Mindanao not under any TCWS. 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:
• “AURING” is forecast to continue moving generally west-northwestward to northwestward throughout the forecast period. On the forecast track and its probability cone, the tropical depression may initially make landfall over the Dinagat Islands-Eastern Samar (southern portion including Homonhon Island)-Leyte area in the next 6 to 12 hours.
• There is an increasing likelihood that “AURING” will further weaken before it makes landfall due to persistent high vertical wind shear associated with the surge of the Northeast Monsoon. Post-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 24 hours, possibly sooner.
Location of eye/center:
At 4:00 AM today, the center of Tropical Depression "AURING" was estimated based on all available data at 195 km East of Maasin City, Southern Leyte (10.3°N, 126.6°E).
Strength:
Maximum sustained winds of 45 km/h near the center and gustiness of up to 55 km/h.
Movement:
Moving West Northwestward at 15 km/h.
Forecast Positions:
• 24 Hour (Tomorrow morning): 55 km West Southwest of Romblon, Romblon (12.4°N, 121.8°E)
