Tropical depression Chedeng organized across the Philippine Sea and will threaten the southern Philippines with flash flooding and gusty winds into Tuesday.

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 been named Chedeng on Sunday.

No additional strengthening is expected as Chedeng will interact with the southern Philippines into Tuesday night.

A continued track to the west will take the storm near the island of Mindanao on Tuesday with the threat for flash flooding and gusty winds.

Heavy downpours began to overspread eastern Mindanao on Monday afternoon. These downpours will intensify and spread westward across the island into Tuesday.

Detailed forecast for Davao

General rainfall amounts across Mindanao 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 Mindanao.

With no additional strengthening expected, widespread wind damage will not occur. Isolated wind damage is possible in any thunderstorms.

Prolonged interaction with land as Chedeng crosses Mindanao will cause weakening of the tropical depression, potentially causing it to dissipate. Drier weather will return to the southern Philippines for the second half of the week.
