Tropical depression to threaten flash flooding in the southern Philippines

By Adam Douty, AccuWeather senior meteorologist




A tropical depression organizing across the Philippine Sea will threaten the southern Philippines with flash flooding and gusty wind early this week.
The system was first called a tropical depression by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Thursday, 14 March. It has since maintained intensity while tracking westward across the Philippine Sea.
While a limited amount of strengthening is possible through the beginning of this week, it is not expected to reach typhoon intensity before making landfall.

Should the system reach tropical storm strength, it would be given the name Chedeng in the Philippines.
A continued track to the west will take the storm near the island of Mindanao from Monday into Tuesday with the threat for flash flooding and gusty wind.
General rainfall amounts across the island through the first half of the week are expected to be 25-75 mm (1-3 inches), though an AccuWeather Local StormMax™ of 150 mm (6 inches) is possible where heavier rainfall persists.
Heavier downpours could move into eastern Visayas, though the threat for flooding will be less compared to farther to the south.
Should the system strengthen into a tropical storm, there could be isolated wind damage where the storm makes landfall along the east coast of Mindanao, though the threat for widespread wind damage will remain low.
Land interactions with the southern Philippines should weaken the depression, potentially causing it to dissipate. Drier weather will return to the southern Philippines for the second half of the week.
