Typhoon "Kiko" (international name "Chanthu") has slightly weakened after its landfall over Ivana, Batanes at around 8:30 a.m., Saturday, Sept. 11.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Kiko now has maximum sustained winds of 205 kilometers per hour (kph) and gustiness of up to 250 kph, from 215 kph maximum sustained winds and gustiness of up to 265 kph before its landfall.
As of 10 a.m., Kiko was over the coastal waters of Itbayat, Batanes, and was moving north-northwest at 15 kph.
PAGASA said the typhoon may pass "very close" to Itbayat, Batanes in the next three hours.
Tropical cyclone wind signal number 4 remains hoisted over Batanes and Signal No. 3 in the northeastern portion of Babuyan Islands.
Signal No. 1 also remains raised over the rest of Babuyan Islands and Signal No. 1 in the northern portion of mainland Cagayan, northern portion of Apayao, and northern portion of Ilocos Norte.
PAGASA said that tropical cyclone wind signals hoisted in other areas have been lifted.
In the next 24 hours, typhoon Kiko will continue to bring heavy to intense with at times torrential rains over Batanes.
Moderate to heavy with at times intense rains may also prevail over Babuyan Islands, Cagayan, Ilocos Norte, Ilocos Sur, Abra, Apayao, and Kalinga.
PAGASA warned against possible scattered to widespread flooding including flash floods and rain-induced landslides in these areas, especially those that are highly susceptible to these hazards.
Typhoon Kiko is also expected to continue to enhance the southwest monsoon or "habagat" and bring monsoon rains over Metro Manila, the rest of Ilocos Region, and the western sections of Central and Southern Luzon in the next 24 hours.
It may exit the Philippine area of responsibility by Sunday evening or early Monday morning, Sept. 13.
