Ten-Day Regional Agri-Weather Information

DEKAD NO. 6  FEBRUARY 21- 28, 2017

PHILIPPINE AGRI-WEATHER FORECAST

The weather systems that will affect the whole country are northeast monsoon, easterlies, low pressure area (LPA) and tail-end of a cold front.

The whole country will have partly cloudy to cloudy skies with isolated rains or thunderstorms during the early days of the forecast period. After this, Mindanao and the regions of MIMAROPA, Eastern Visayas and Central Visayas will have light to moderate rains and thunderstorms. The regions of Cagayan Valley, Ilocos, CAR, Central Luzon and Bicol will experience cloudiness which may bring rains or thunderstorms at the midst of the forecast period up to the latter part of the dekad. The rest of the country will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms.

Light to moderate winds will blow from east to southeast over Luzon during the early days of the dekadal period. After this, gradual shift to northeasterly direction of moderate to strong winds will prevail over Luzon. The rest of the country will have winds coming from east to northeast.

During the early days of the forecast period, the seaboards of the whole country will be slight to moderate. The coastal waters of Luzon will be moderate to rough at the midst of the forecast period. This will take place up to the latter part of the dekad. The rest of the country will have slight to moderate seas.

The eastern and central equatorial Pacific is in neutral condition.

Oceans and seas have great influence on the weather of continental masses. A large portion of the solar energy reaching the sea-surface is expended in the process of evaporation. These water evaporated from the sea/ocean is carried up into the atmosphere and condenses, forming clouds from which all forms of precipitation result. Sometimes, intense cyclonic circulations occur which is what we call the tropical cyclones.

PSWS UpdatedWhen any Tropical Cyclone Warning Signal (TCWS) Number is hoisted or put in effect for the first time, the corresponding meteorological conditions are not yet prevailing over the locality. This is because the purpose of the signal is to warn the impending occurrence of the given meteorological conditions. It must be noted also that the approximate lead time to expect the range of the wind speeds given for each signal number is valid only when the signal number is put in effect for the first time. Thus, the associated meteorological conditions are still expected in at least 36 hours when TCWS #1 is put in effect initially; in at least 24 hours with TCWS #2; in at least 18 hours with TCWS #3, in at least 12 hours with TCWS #4; and in at least 12 hours with TCWS #5. The lead time shortens correspondingly in the subsequent issues of the warning bulletin when the signal number remains in effect as the tropical cyclone comes closer.

REVISED LIST OF NAMES FOR TROPICAL CYCLONES WITHIN THE
PHILIPPINE AREA OF RESPONSIBILITY (Effective January 2017)

The first tropical cyclone of the year starts with the name beginning in letter A as in AURING under column 1 for 2017 and so on down the list as one disturbance succeeds another.  The 5th year (2021) will bring us back to column 1 of AURING.  In the event that the  number of tropical cyclones within the year exceeds 25, an auxiliary list is used, the first ten of which are listed under each column.

The Typhoon Committee, recently released a list of 140 tropical cyclone names adopted by its Members for use in the Western North Pacific Ocean and the South China Sea. The new naming system, which will lead to the standardization of the usage of names for tropical cyclones in the region, was approved during the 31st session of the Committee, held in the Philippines on 1-7 December 1998. This scheme is also expected to enhance alertness of the people to impending tropical cyclone hazard. The new method of assigning Asian names to tropical cyclones in the region will be implemented at the start of the new millenium on 1 January 2000.
