Hopeless Pag-asa X

Reports say PNoy criticized the PAGASA for not warning the residents of Metro Manila about a strong tropical storm that pummeled the nation's capital. Hopeless PAGASA had it coming. Our weather bureau could have used a dart board in predicting the weather and it might have gotten better results. They are that bad.

PAGASA's own website says public storm signal no. 1 is raised when winds of 30-60 kph may be expected in at least 36 hours or intermittent rains may be expected within 36 hours. Public storm signal no. 2 is hoisted when winds of greater than 60 kph and up to 100 kph may be expected in at least 24 hours. This is summarized in the Philippine's first website on tropical cyclones.

What did PAGASA do this time to deserve the presidential ire?

They wrongly predicted the places where typhoon Basyang will hit. They raised signal no. 1 in Metro Manila. When winds over 100kph started to batter the metropolis, they hastily upped it to signal no. 2, only to quickly lower it back to no. 1 after 6 hours, when the typhoon  has passed. You raise public storm signals to notify residents of impending weather disturbances, so they can prepare for contingencies. With its performance, PAGASA does not forecast the weather, it describes the weather. Last night when they raised signal no. 2, they did not mean to forecast winds up to 100kph will come in 24 hours. They meant to describe the winds we have now at 100kph as signal no. 2 category.
