At 4:00 am today, the center of Tropical Depression ‘Amang’ was estimated based on all available data over the coastal waters of San Andres, Catanduanes.
‘Bagyong Amang’ has a maximum sustained winds of 45 km/h near the center, gustiness of up to 60 km/h, and central pressure of 1006 hPa.
It is moving west northwestward at 20 km/h.
Strong winds extend outwards up to 200 km from the center.
TROPICAL CYCLONE WIND SIGNALS (TCWS)
TCWS No. 1 (Strong winds prevailing or expected within the next 36 hours)
- Camarines Sur
- Camarines Norte
- Ticao Island
- Burias Island
- the eastern portion of Laguna (San Pablo City, Rizal, Nagcarlan, Pila, Liliw, Magdalena, Majayjay, Luisiana, Cavinti, Pagsanjan, Santa Cruz, Lumban, Kalayaan, Paete, Pakil, Pangil, Siniloan, Famy, Santa Maria, Mabitac)
- the eastern portion of Rizal (Tanay, Pililla, Jala-Jala)
TRACK AND INTENSITY OUTLOOK
‘Amang’ is forecast to tracking generally westward or west northwestward in the next 24 hours, which will bring its center over the Camarines Provinces, Lamon Bay, and mainland Quezon with the possibility of passing near or over Polillo Islands.
Considering the weak and disorganized nature of this depression, northward or southward shifts in the track forecast of succeeding bulletins are not ruled out.
The tropical depression is forecast to weaken into a low pressure area by tomorrow, possibly earlier, due to the combined effects of land interaction, dry air intrusion, and increasing vertical wind shear.
HAZARDS AFFECTING LAND AREAS
Heavy Rainfall Outlook
Forecast accumulated rainfall from this early morning until tomorrow early morning
- 50-100 mm: Camarines Provinces and the southeastern portion of Quezon
Forecast accumulated rainfall from this early morning until Saturday early morning
- 50-100 mm: Camarines Provinces, Quezon, Laguna, and Rizal
Under these conditions, isolated flashfloods and rain-induced landslides are possible, especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
Areas under Wind Signal No. 1 may experience strong winds (strong breeze to near gale strength) associated with the tropical depression which may cause minimal to minor impacts to life and property.
HAZARDS AFFECTING COASTAL WATERS
In the next 24 hours, moderate to rough seas may be experienced over the eastern and southern seaboards of Southern Luzon (1.5 to 3.5 m) and the eastern seaboard of Central Luzon (1.5 to 2.8 m).
Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions.
‘Bagyong Amang’ is the first tropical cyclone for 2023, developed from Low Pressure Area (LPA) east of Catanduanes on Tuesday, April 11, 2023.
On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.
