Tropical Cyclone Wind Signal (TCWS) No. 3 remained hoisted over the northern portion of Batanes, particularly in the municipality of Itbayat, as Typhoon Jenny maintained its strength late Wednesday morning, according to state weather bureau PAGASA.
Based on its 11 a.m. bulletin, PAGASA said the center of the eye of Jenny was estimated at 210 kilometers northeast of Itbayat.
Due to this, storm-force winds ranging from 89 to 117 km/h may prevail over Itbayat in the next 18 hours. Wind impacts may result in moderate to significant threat to life and property.
TCWS No. 2, meanwhile, was raised over the rest of Batanes and the northern portion of Babuyan Islands (Babuyan Is., Calayan Is.).
With this, gale-force winds ranging from 62 to 88 km/h may occur in these areas within the next 24 hours. Wind impacts may also result in minor to moderate threat to life and property.
The following areas, on the other hand, are under TCWS No. 1:
- The rest of Babuyan Islands,
- the northern portion of mainland Cagayan (Santa Ana, Gonzaga, Buguey, Santa Teresita, Lal-Lo, Camalaniugan, Pamplona, Claveria, Aparri, Ballesteros, Abulug, Allacapan, Sanchez-Mira, Santa Praxedes, Lasam, Gattaran),
- the northern portion of Apayao (Calanasan, Pudtol, Luna, Santa Marcela, Flora), and
- the northern portion of Ilocos Norte (Piddig, Bangui, Vintar, Burgos, Pagudpud, Bacarra, Adams, Pasuquin, Carasi, Dumalneg, Laoag City).
Strong winds from 39 to 61 km/h may be expected in these areas within the next 36 hours. Wind impacts may result in minimal to minor threat to life and property.
PAGASA said Jenny has a maximum sustained winds of 150 km/h near the center, gustiness of up to 185 km/h, and central pressure of 955 hPa. It was moving west northwestward at 15 km/h.
Strong to typhoon-force winds also extend outwards up to 560 km from its center.
The state weather bureau said Jenny will continue to enhance the Southwest Monsoon (Habagat) and bring occasional rains over the western portions of Luzon in the next three days.
The typhoon is also expected to move westward, make landfall over the southern portion of Taiwan on Thursday morning, then exit the Philippine Area of Responsibility (PAR) in the afternoon or evening.
Outside the Philippine Area of Responsibility, Jenny will continue to move westward slowly over the Taiwan Strait and the coastal waters of southeastern China.
“The weakening trend is forecast to continue due to the increasing dry air entrainment and vertical wind shear. Land interaction during its passage over the rugged terrain of southern Taiwan will further weaken the typhoon,” PAGASA said.
“Once over the Taiwan Strait, additional cool dry air from the north will entrain into JENNY, resulting in continued weakening,” it added. —Giselle Ombay/KBK, GMA Integrated News
