MANILA - State weather bureau PAGASA said the country will start experiencing improved weather after typhoon "Henry" leaves.
This will not last long, however, since another potential cyclone is expected to bring rains next week.
In its 5 p.m. weather bulletin on Tuesday, PAGASA said Henry has slightly weakened, now packing maximum sustained winds of 130 kilometers per hour (kph) near the center and gustiness of up to 160 kph.
It was spotted 170 kilometers north of Basco, Batanes as of 4 p.m. It was moving towards the Taiwan area at 24 kph.
Batanes Group of Islands remains under public storm warning signal number 2. It should expect winds of 61 to 100 kph in at least 24 hours.
Babuyan and Calayan Group of Islands, meanwhile, are under storm signal number 1, and should expect winds of 30 to 60 kph in at least 36 hours.
The typhoon is estimated to bring 7.5 to 15 millimeters per hour (moderate to heavy) of rainfall within its 500-kilometer diameter.
It is also causing moderate to occasionally heavy rains over Ilocos Region, Cordillera Administrative Region, and the provinces of Zambales and Bataan.
The rest of Luzon and Western Visayas, meanwhile, are experiencing monsoon rains.
Residents in these areas are advised to be on alert against possible flashfloods and landslides. Fisherfolks and those with small seacrafts are also advised not to venture out over the seaboards of Luzon and Western Visayas.
Inday to bring rains next week
According to PAGASA, Henry, which did not make landfall in any part of the country, is expected to be outside the Philippine area of responsibility (PAR) on Wednesday morning.
But even if it is already outside PAR, it will continue to enhance the southwest monsoon (habagat).
PAGASA weather forecaster Alvin Pura told radio dzMM that the weather will only start to gradually improve by Friday morning.
However, the good weather will not last long since another low pressure area (LPA) off Visayas may intensify into tropical cyclone "Inday" and enter PAR this weekend.
"Pag dumating na po si Inday at humila yan ng habagat, posibleng next week po magiging maulan pa rin po tayo," Pura said.
The LPA was last spotted 1,300 kilometers east of Visayas. Pura said it has a high chance of developing into a cyclone.
"Inaasahan natin na by weekend siya papasok or didikit diyan sa ating PAR boundary line."
"Kung sakali pong maging bagyo ito, posibleng daanan niya yung dinaanan ni Florita at Henry, pa-northwest, diyan pa-China at Japan area," Pura said.
