The low-pressure area tracked over the east of Central Luzon has entered the Philippine area of responsibility (PAR) and developed into Tropical Depression Jenny, the state weather bureau said Friday.
In its latest weather bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration reported that the LPA entered the country and developed into a tropical depression around 2 p.m. on Friday.
PAGASA said TD Jenny is not directly affecting the country.
However, it is expected to bring heavy rains over Batanes and Babuyan Islands in the next five days.
PAGASA said TD Jenny may enhance the Southwest Monsoon or 'habagat' beginning on Sunday, resulting in possible occasional rains over the western portions of Central and Southern Luzon.
The tropical depression is forecast to track generally westward or west-northwestward until Saturday before turning further north over the Philippine Sea east of Northern and Central Luzon.
It will then be expected to have a close approach over the Batanes area by Wednesday.
PAGASA sees the TD may landfall over Batanes-Babuyan or northeastern mainland Cagayan.
Jenny is also expected to steadily intensify throughout the forecast period and may reach the tropical storm category tomorrow afternoon.
It may be upgraded into a typhoon category by Wednesday during its close approach over the Batanes area.
Jenny is currently moving westward at 20 kilometers per hour with maximum sustained winds of 45 kph near the center and gustiness of up to 55 kph.
No tropical cyclone wind signal is currently hoisted.
