Ten-Day Regional Agri-Weather Information

DEKAD NO. 15 May 21 - 31, 2017

PHILIPPINE AGRI-WEATHER FORECAST

The weather systems that will affect the whole country are frontal system, easterlies, southwest monsoon and intertropical convergence zone (ITCZ).

Throughout the dekadal period, Northern Luzon especially Ilocos Region, CAR, Cagayan Valley will be cloudy with light to moderate rains and isolated thunderstorms. Mindanao will experience cloudy skies with rainshowers and isolated thunderstorms due to enhanced convection brought by ITCZ. While the rest of the country will have fair weather with possible isolated rainshowers or thunderstorms mostly in the evening or afternoon.

Light to moderate winds coming from southeast to east will prevail over Mindanao, Visayas and eastern section of the country and from southwest over western section especially of Northern Luzon.

During the forecast period, the coastal waters throughout the whole country will be 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 Public Storm Warning Signal 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 PSWS #1 is put in effect initially; in at least 24 hours with PSWS #2; in at least 18 hours with PSWS #3, in at least 12 hours with PSWS #4; and in at least 12 hours with PSWS #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.

PRESS RELEASE
24 May 2017

START OF SOUTHWEST MONSOON

Southwesterly windflow has been dominant over the West Philippine Sea for several days now. This is due to the formation of semi-permanent trough over Northern Luzon-Taiwan area and the eastward migration of the North Pacific High Pressure Area which are the prominent indicators of the southwest monsoon onset in the country. 

Likewise, the prevailing weather condition in most parts of Luzon and Visayas particularly the western section is now warm and humid as characterized by occasional to frequent occurrences of afternoon-evening or early morning rainshowers and thunderstorms. These developments signify the approaching onset of rainy season under Type 1 climate covering the western parts of Luzon and Visayas.
