Weather Forecast Olongapo-Subic

Be ready for flooding, may not be as bad as Ondoy but could be somewhere near it.

Olongapo City 1 – 3 Day Weather Forecast Summary: Heavy rain (total 278mm), heaviest during Fri night, Wind will be generally light.

250mm and above precipitation means flooding in our city.

While PAGASA Enhanced Satellite Image and Track of Storm Juaning indicate lesser disturbance prompting them to lower storm warning signals. This observer believe that such public announcement can be detrimental to our constituency in Olongapo City because people may lower their guards thinking that the worst is over.....

PAGASA's focus is on the strenght and movement of the storm. This writer's focus is on anticipating the volume of water that will pour in Olongapo City, a flood prone locality.

NASA's Tropical Rainfall Measuring Mission predicts that we will be flooded.

International Weather forecasts indicate that we will be flooded tomorrow afternoon til night.... I have been reading their forecast for years.... and this is one of the very few instances when a 97mm precipitation forecast was raised.

Tide charts are provided below for added reference.

“The Philippines has the highest number of tropical typhoons in the world with an average of 20 typhoons entering the country every year, so we must always prepare for the worst situations,” said Mayor James “Bong” Gordon, Jr.

According to the Philippine Atmospheric Geophysical and Astronomical Services Administration or PAG-ASA,

Public Storm Signal No. 1 is put into effect when a maximum wind speed of not more than 60 kph is expected to affect a certain place in at lest 36 hours. In this situation, impact of winds may cause twigs and branches of small trees to be broken, some banana plants may be tiled or downed and some houses of very light materials like nipa and cogon may be partially unroofed. Classes in pre-school level in all public and private schools in affected communities will automatically be suspended.

On the other hand, Public Storm Signal No. 2 is announced when the maximum wind speed is greater than 60kph but not more than 100 kph is expected to affect a certain place in at least 24 hours. In this situation some coconut trees may be tilted or broken, few big trees may be uprooted, large number of nipa and cogon houses may be partially or totally unroofed, some old galvanized iron roofing may be peeled off and in general, the winds may bring light to moderate damages to the communities affected. With storm signal no. 2, classes in pre-school, elementary and high school levels in all public and private schools in affected areas are automatically suspended .

Public Storm Signal No. 3 is announced when a maximum wind speed of more than 100 kph up to 185 kph is expected to affect a certain place in at least 12 to 18 hours. In this situation, nipa houses may be unroofed or destroyed and there may be considerable damages to structures of light to medium construction. There may be widespread disruption of electrical power and communication services and in general, moderate to heavy damage may be expected, practically in agricultural and industrial sectors. With public storm signal no. 3, people are advised not to travel especially by sea or air transportation and people should also seek shelter in strong buildings, evacuate low-lying areas and stay-away from seacoasts or river banks.
