Typhoon Hanna officially left the Philippine Area of Responsibility (PAR) on Monday morning, September 4, but the enhanced southwest monsoon or habagat will continuously bring rains in some areas of Luzon.

According to its latest bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Hanna exited the PAR at 8 AM.

At 10 AM, Hanna was tracked 360 kilometers (km) Northwest of Itbayat, Batanes, with 120 km per hour (kph) winds and 165 kph gusts.

The typhoon is heading in north northwestward direction at 15 kph speed and is forecasted to accelerate west northwestward over Taiwan Strait and make landfall over the coast of Guangdong or Fujian in China by Tuesday.

"Rapid weakening will ensue as the tropical cyclone moves further inland over Guangdong, China. HANNA is forecast to become a remnant low on late Wednesday or Thursday," the state weather bureau said.

PAGASA lifted the Tropical Cyclone Wind Signal (TCWS) No. 1 in Batanes.

Habagat-induced rains and winds

In the next three days, the western portion of Luzon will experience occasional monsoon rains induced by Hanna-enhanced southwest monsoon.

In its weather advisory No. 22 for Southwest monsoon, PAGASA said Metro Manila, Ilocos Norte, Ilocos Sur, La Union, Abra, Benguet, Tarlac, Nueva Ecija, Pampanga, Bulacan, Rizal, Cavite, Batangas, Occidental Mindoro, and Calamian Island will have 50 to 100 millimeters of rainfall today.

Meanwhile, 100 to 200 milimeters of rainfall will be felt in Pangasinan Zambales, and Bataan.

Gusty conditions will dominate today in Batanes, Babuyan Islands, Ilocos Region, Cordillera Administrative Region, Nueva Vizcaya, the southern portion of Aurora, Zambales, Bataan, Bulacan, Metro Manila, Occidental Mindoro, Romblon, Marinduque, the northern portion of Palawan including Calamian, Kalayaan, and Cuyo Islands, and most of CALABARZON, Bicol Region, and Western Visayas.

The seaboards of Northern Luzon, the western and southern seaboards of Luzon, and the western seaboard of Visayas remained under the influence of gale warnings due to hazardous sea conditions brought by Hanna and enhanbced southwest monsoon.
