Ten-Day Regional Agri-Weather Information

DECADE NO. 2  JANUARY 11- 20, 2017

PHILIPPINE AGRI-WEATHER FORECAST

The weather systems that will affect the whole country are northeast monsoon, LPA (previously Tropical Depression Auring) and tropical cyclone.

During the early days of the ten-day forecast, Northern Luzon will experience light rains while the cloudiness associated with the LPA will continue to bring rains and thunderstorms over Visayas, CALABARZON, and the regions of Bicol and MIMAROPA. Gradual improvement of weather over these areas is expected afterwards. As the LPA (formerly TD Auring) moves outside the Philippine Area of Resposibility (PAR), another LPA at the east of the country is predicted to enter PAR. This LPA may develop into a tropical cyclone at the midst of the forecast period but will not have direct effect in the country. It will move in a north northwest direction before going in a north northeast track. Light rains are expected over the eastern section of Luzon and Visayas as the northeasterly wind flow start to strengthen again.  Southern Luzon and Visayas are expected to have rains with thunderstorms at the midst of the forecast period while the rest of Luzon will have light rains. The rest of the country will have good weather. During the last part of the decade, partly cloudy to cloudy skies with isolated thunderstorms will prevail over the whole archipelago.

Gradual decrease of temperature is expected over Northern and Central Luzon at the midst of the forecast period. This condition will continue throughout the remaining days of the decade.

Moderate to strong winds will prevail over Luzon while light to moderate winds will blow over Mindanao throughout the decade. During the first half of the forecast period, Visayas will have light to moderate winds. Visayas will have moderate to strong winds during the remaining days of the ten-day period.

Visayas and Mindanao will have slight to moderate seas during the first half of the decade. Afterwards, the coastal waters over Visayas will be moderate to rough while Mindanao will have slight to moderate seas. The seaboards over Luzon will be moderate to rough throughout the ten-day period.

The eastern and central equatorial Pacific is in neutral condition.

Telescoping and stargazing 
The PAGASA Astronomical Observatory is located inside the campus of the University of the Philippines, Diliman, Quezon City, conducts stargazing and telescoping sessions to interested astronomy enthusiasts, upon request. The session can either be conducted at the Observatory or at a specified venue of the requesting party/ individual. Letter of request should reach the Office of the Chief, Space Science and Astronomy Section, at least two weeks earlier than scheduled time, especially those, which will be conducted outside the PAGASA Observatory to allow the processing of necessary documents. The request letter can be addressed to:

Dr. Vicente B. Malano
Acting Administrator, PAGASA
Science Garden
Agham Road, Diliman
Quezon City, Philippines 1100

ATTENTION: Engr. Dario L. dela Cruz
                       Chief, SSAS

During the previous years, the 30-cm reflector-type telescope, which was permanently installed at the Observatory dome, is being used for the telescoping sessions. However, in May 2001, the Japanese Government donated a computer-based 45-cm telescope and was installed at the Observatory. Starting on February 16, 2003, the start of the celebration of the National Astronomy Week, the telescope is open for public use, after a series of adjustments made by the Japanese technicians.

Provided that the sky is clear, visitors can expect to have a glimpse of the famous bright stars like Vega and Sirius during the stargazing session. Planets such as Jupiter, Venus, Saturn, Mercury and Mars, including their satellites and the Moon can also be observed.

For residents of the cities of Davao, Cagayan de Oro, Cebu and Legazpi, stargazing and telescoping sessions can also be conducted at the PAGASA regional centers located in their area. One (1) 25-cm telescope in each of the above-mentioned sites are available for use. These telescopes were procured in May 1998 through the Grant-in-aid (GIA) project of the Department of Science and Technology (DOST), which is entitled "Promotion of Astronomy".
