In July 2010, the Philippines were hit by Typhoon Basyang, the second tropical cyclone during the 2010 Pacific typhoon season to impact the nation.
Conson was poorly forecast by PAGASA. From July 12 to 13, Conson was forecast to hit Aurora and Isabela provinces. But, at 11 pm PST (1500 UTC) on July 13 PAGASA changed its forecast from hitting Aurora and Isabela provinces, to Quezon province, Metro Manila and southern Luzon provinces. However, residents living in those areas were not advised that the typhoon would hit their area and they also were not informed that public storm signal number 2 was raised. With this, severe damage ensued in the said areas. Later that same day, President Benigno Aquino III reprimanded PAGASA for failing to predict that Conson would pass over Manila.[6]
As a result, Aquino criticized PAGASA for not warning the residents of Metro Manila about the strong tropical storm that struck the nation's capital.[7] However, according to Dr. Nilo and PAGASA, the agency didn't have adequate equipment to "accurately" predict a movement of a storm and the weather forecasting instruments were too old and needed to be upgraded.
