Typhoon 'Nina' moves away from Philippines, another storm spotted-A A +A
Monday, October 15, 2012
MANILA -- Typhoon "Nina" has slightly weakened as it continued to move slowly away from the country, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said on Monday.
Pagasa weather forecaster Fernando Cada said the typhoon’s winds strength decreased from 140 kilometers per hour (kph) Sunday to 130 kph on Monday, while its gustiness also fell from 170 kph to 160 kph.
As of 4 a.m., the center of Nina was located at 870 kms northeast of Itbayat, Batanes (23.0°N, 131.2°E) and it is forecast to move northwest at 5 kph.
With this speed, Duran said that Nina will likely exit the Philippine Area of Responsibility (PAR) either Tuesday or Wednesday.
Cada said that Nina's weakening was still because of a ridge of high pressure area near China as well as vertical wind shear or different directions of winds that drifts into the country.
Since the country is in the transition period from southwest monsoon (habagat) to northeast monsoon (amihan), Cada said that winds in various directions blow off into the country, which affects the circulation of the typhoon.
The southwest monsoon is the prevailing weather system in the country during rainy season or from June to early October.
While the northeast monsoon or the “winterwinds” normally starts during mid-October and ends in mid-February.
This year, Cada said the onset of the northeast monsoon will likely start during later part of this month, which would also signal the termination of the southwest monsoon season.
He added that no storm warning signal has been raised so far, since Nina still remained too far to directly affect any part of the country.
Meanwhile, Cada said the weather agency spotted another tropical storm in Guam with international name "Maria".
This will most likely not enter the country within two to three days, he said.
But once the storm enter the PAR, it will be called “Ofel”, the 15th tropical cyclone to enter the country this year.
Meanwhile, Cada said Metro Manila and the rest of the country will generally have good weather until Tuesday except for possible brief rainshowers mostly in the afternoon or evening due to localized thunderstorms.
Cada said the regions of Zamboanga and Davao and the provinces of Palawan, South Cotabato, Lanao Del Norte, Lanao Del Sur and Bukidnon will experience light to moderate rains.
Pagasa said strong to gale force wind is expected to affect the seaboards of northern Luzon and the eastern seaboard of central and southern Luzon.
Fishing boats and other small seacrafts are advised not to venture out into the sea while larger vessels are alerted against big waves.
Pagasa said moderate to strong winds blowing from the north to northwest will prevail over northern and eastern Luzon.
The coastal waters along these areas will be moderate to rough.
Meanwhile, winds will be light to moderate coming from the north to northeast over western Luzon and southeast to southwest over the rest of the archipelago with slight to moderate seas. (PNA)
