    While over the West Philippine sea, the typhoon is forecast to move west northwestward and may exit the Philippine Area of Responsibility this morning or afternoon.

    'Bagyong Odette' PAGASA weather update December 18, 2021

    'Odette' is forecast to pass in the vicinity of Kalayaan Islands today. A slight re-intensification may take place today as 'Odette' moves over the West Philippine Sea. However, the eventual exposure of the typhoon to increasing vertical wind shear and the surge of the Northeast Monsoon will result in a weakening trend beginning tomorrow.

    HAZARDS AFFECTING LAND AREAS

    Heavy Rainfall

    Today: Heavy to torrential rains over Kalayaan Islands. Moderate to heavy rains over mainland Palawan, Aurora, and the northern portion of Quezon including Polillo Islands. Light to moderate with at times heavy rains over Bicol Region, Northern Samar, Nueva Vizcaya, Quirino, Nueva Ecija, and the rest of Quezon.

    Under these conditions, scattered to widespread flooding (including flash floods) and rain-induced landslides are expected especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps, and in localities with significant antecedent rainfall.

    Severe Winds

    Destructive typhoon-force winds will be experienced within any of the areas where TCWS #3 is in effect. This may bring moderate to heavy damage to structures and vegetation.

    Damaging winds reaching gale- to storm-force strength will be experienced within any of the areas where TCWS #2 is in effect. This may result in generally light to moderate damage to structures and vegetation.

    Strong winds (strong breeze to near gale) with higher gusts will be experienced within any of the areas where TCWS #1 is currently in effect during the passage of the typhoon. This may generally bring up to very light damage to structures and vegetation.

    Coastal Inundation

    There is still a moderate to high risk of storm surge which may result in life-threatening coastal flooding in Kalayaan Islands. In addition, coastal areas of localities under TCWS #2 and #1 may also experience coastal flooding due to hazardous surf conditions.

    HAZARDS AFFECTING COASTAL WATERS

    In the next 24 hours, rough to very high seas (2.8 to 10.0 m) will be experienced over the seaboards of areas where TCWS #3 is in effect (especially in the open sea areas). Rough to very rough seas (2.8 to 5.0 m) will also continue for the seaboards of areas under TCWS # 2 and #1. These conditions are risky for all types of sea vessels. Mariners are advised to remain in port or take shelter in port until winds and waves subside.

    Under the influence of Typhoon 'Odette' and the prevailing Northeast Monsoon, a Gale Warning remains in effect for several coastal waters not under any wind signal, specifically the seaboards of Northern Luzon, and the eastern and western seaboards of Central and Southern Luzon.

    Moderate to rough seas (1.2 to 4.0 m) will also prevail over the remaining seaboards of the country that are not under any wind signal or gale warning, specifically the seaboards of Visayas and the northern, western, and eastern seaboards of Mindanao. These conditions are risky for those using small seacrafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions.

    TROPICAL CYCLONES

    'Odette', the 15th tropical cyclone this year, entered the Philippine Area of Responsibility (PAR) at 7 pm on Tuesday, December 14.

    On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.

    The weather agency declared the onset of the rainy season on Friday, June 5.
