Typhoon AGHON (EWINIAR) Advisory No. 09

48-hr Outlook:  Over the next 24 hours, Aghon is expected to hold steady or even strengthen slightly as it accelerates northeastward away from Luzon. However, on Wednesday afternoon (May 29th), as the typhoon nears the edge of the Philippine Area of Responsibility (PAR), unfavorable atmospheric conditions will weaken Aghon significantly, potentially downgrading it to a minimal Category 1 typhoon. 

Even though Typhoon AGHON itself is moving away, its outer rainbands will continue to bring cloudy skies with periods of severe thunderstorms to the eastern sections of Central and Northern Luzon tonight. Residents in these areas are advised to take necessary precautions against potential flooding, landslides, and lahars.
