Latest advisory from the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) states that as of 8:00 A.M. today, September 12, 2018, the eye of Typhoon “Mangkhut” (Typhoon “Ompong”) was estimated based on all available data at 1,190 km. east-northeast of Guiuan, Eastern Samar (outside PAR) (13.8°N, 136.3°E) with a maximum sustained winds of up to 205 kph near the center with gustiness of up to 255 kph. It is moving west at 20 kph. Forecast position as of tomorrow morning September 13, 2018 is at 805 km east of Virac, Catanduanes (14.8˚N, 127.2˚E) moving outside PAR towards the northwest at 590 km west of extreme Norther Luzon (20.4˚N, 116.3˚E) on Sunday morning, September 16, 2018.
Tropical Cyclone Signal #1 (TCWS#1) maybe raised over Eastern Luzon as early as tonight or tomorrow early morning September 13, 2018. Heavy rains and strong winds brought about by Typhoon “Ompong” over Northern Luzon and parts of Central and Southern Luzon may intensify the southwest monsoon (“Habagat”) which may bring occasional moderate to heavy rains over Central Visayas by Wednesday and Thursday and windy to light to moderate rains from Friday to Saturday. This could trigger flashfloods in low lying areas along river systems or landslides along mountain slopes.
The Philippine Coast Guard advised that sea travel for Cebu and Bohol Provinces will be suspended by tomorrow September 13, 2018, starting 12:00 noon or earlier if weather worsens.
Local government units in areas Identified as susceptible to landslide, flooding and coastal flooding during the geohazard mapping in Central Visayas are recommended to take precautionary measures. They are also advised to use the information, findings and recommendations provided along with the geohazard maps to enhance efforts in reducing the possible effects of the impacts of Typhoon Ompong. Also, areas near or along rivers, creeks and drainage channels are likely to be affected by flashfloods during extreme weather conditions.
MGB-7 Director Loreto B. Alburo pointed out that pre-emptive actions should be carried out in those areas which have been declared as “susceptible” to either landslide or flooding. Constituents living along or near rivers, creeks, water channels and coastal areas are also at high risk to flooding hazards while those living on sloping areas and along foot slope of mountains are susceptible to rain-induced landslides.
