Tropical Storm Jangmi made landfall earlier this morning along coastal Surigao del Sur.  Currently, it has emerged north of Mindanao as it continues moving west-northwest toward the Central and Western Visayas.

Storm Update (1)

Although, Jangmi remains barely a tropical storm, the main threat will continue to be significant rainfall as this system slowly tracks westward.  Hardest affected so far appears to be the Caraga region of Mindanao.  Specifically, between Saturday at 8 am (PhST) and Monday at 2 pm, Hinatuan, Surigao del Sur, received 504.2 mm (19.85″); Surigao City, Surigao del Norte, received 223.8 mm (8.81″); Butuan, Agusan del Norte, received 217.8 mm (8.57″); and Punta Maria Borongan, Eastern Samar, received 217.0 mm (8.54″).

Seniang ra

Currently, there are reports of widespread landslides across northeastern Mindanao while thousands are evacuating their homes.    NDRRMC is not reporting casualties at this time; however, media is reporting varied amounts between 1-3 deaths at this time ranging from drownings to accidents.  Unfortunately, given the reports of flooding and landslides–especially close to population–this number may raise.  We received the following video of flooding along the Cagayan de Oro river where water levels have rose rapidly:

Moving forward, the rain threat will continue moving westward toward Siquijor and Negros Oriental throughout the day on Tuesday.  We should see a shift in the track toward the west-southwest thanks to building high pressure across the South China Sea.  Near term–this means southern Palawan will see the center move toward them.  However, we shouldn’t focus on the center track considering the rain extends well away from the center of circulation and will be a factor for most throughout the Visayas and southern Luzon.  Long term–the west-southwesterly track will cause the storm to move toward western Malaysia where they have been dealing with their own heavy rain problem lately.  Jangmi appears poise to further compound the problem there.
