Based on the Tropical Cyclone Advisory #6 issued by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) as of 11:00 AM of December 14, 2021, “RAI” intensifies into a severe tropical storm while moving west-northwestward towards Palau.
The center of the Severe Tropical Storm “RAI” was estimated based on all available data at 1,165 km East of Mindanao (7.3°N, 136.4°E) (outside the PAR). Maximum sustained winds of 95 km/h near the center, gustiness up to 115 km/h, and central pressure of 990 hPa
Under these conditions and considering antecedent rainfall, scattered flooding (including flash floods) and rain-induced landslides are highly likely, especially in areas with high or very high susceptibility to these hazards as identified in hazard maps. Adjacent or nearby areas may also experience flooding in the absence of such rainfall occurrence due to surface runoff or swelling of river channels.
The Mines and Geosciences Bureau Regional Office No. VI advises the public and the disaster risk reduction management offices to continuously monitor the updates on this severe tropical storm and prepare for the possible occurrences of landslides and floods. LGUs are advised to refer to the Mines and Geosciences Bureau Geohazard Maps distributed to the respective municipalities and cities and take precautionary measures especially in high-risk areas where possible evacuations are really necessary.
