HAZARDS:

  • At most Heavy to intense with at times torrential rains over Eastern Visayas and DinagatIslands.

  • Severe winds (gale-force in strength) especially in areas where TCWS no. 2 is hoisted throughout the passage of TS MEGI (Agaton)

  • Under these conditions and considering the significant antecedent rainfall, scattered to widespread flooding and rain-induced landslides especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps.

IMPACTS: According to the National Disaster Risk Reduction and Management Council (NDRRMC)

  • 38,399 families (45,588 persons) have been affected from 106 Barangays in the following Regions: 10, 11, CARAGA, and BARMM

PREPAREDNESS AND RESPONSE:

  • NDRRMC raised its alert status to RED on 8 April 2022,1700 HRS UTC+7 in response to the impacts of TS MEGI (Agaton)

  • Meetings among the Pre-Disaster Risk Analysis (PDRA) group, core group, NDRRMC member agencies, and Office of Civil Defense have been facilitated

  • Continuous monitoring and dissemination of early warning information and advisories through SMS, social media, and official channels down to the Local Disaster Risk Reduction and Management Councils (LDRRMC)

OUTLOOK:

  • TS MEGI (Agaton) made landfall over Calicoan Island, Guiuan, Eastern Samar at 0630 HRS UTC+7 today

  • Today (10 Apr) through early Tuesday (12 Apr), TS MEGI (Agaton) is forecast to move erratically or remain almost stationary over the southern portion of Samar Island and its coastal waters due to weak steering movement. Due to the expected erratic movement, a westward shift in track is possible. Thus, TS MEGI (Agaton) may move over the coastal waters or may make another landfall in Leyte.

  • By mid-Tuesday (12 Apr), TS MEGI (Agaton) will gradually accelerate, turn east-southeastward or eastward as the tropical storm interacts with Tropical Cyclone (TC) MALAKAS currently located in the NorthwestPacific Ocean.

  • TS MEGI (Agaton) will likely remain a Tropical Storm for most of the forecast period, but the downgrading to Tropical Depression is not ruled out due to potential interaction with land. o TS MEGI (Agaton) is forecast to degenerate into a remnant low by late Tuesday (12 Apr) or early Wednesday (13 Apr) as TC MALAKAS begins to assimilate its circulation

The AHA Centre will continue to monitor and issue necessary updates once more information from official sources becomes available.
