New tropical threat in West Pacific may impact Philippines, Taiwan

An area of showers and thunderstorms to the east of the Philippines will drift northward through Wednesday and is expected to become the next tropical system in the west Pacific.

If the budding system reaches tropical storm strength, it will be given the name Nesat and become the fifth named storm in the basin within a week's time.


Locations from the northern Philippines to Taiwan should be on alert for potential impacts this week ranging from flooding rainfall to damaging winds.

The biggest concern across the Philippines will be heavy rainfall as the developing cyclone passes east of Luzon this week.
This will create a strong easterly flow, pulling ample moisture into the island causing torrential downpours from Wednesday into this weekend.

Flash flooding and mudslides will be possible across Luzon with an increased risk each day as downpours continue over the same areas.
The threats for Taiwan are less clear and will be dependent on development, strength and track of this potential cyclone.

“Taiwan appears to be the most likely target of this tropical threat,” AccuWeather Meteorologist Adam Douty said.

The potential exists for this budding tropical threat to intensify into strong tropical storm or typhoon before reaching Taiwan bringing a high risk for flash flooding and damaging winds.

Another scenario would have the cyclone remaining weak and continuing on a northerly track which would keep any impacts to the east of Taiwan.

Elsewhere in the basin, Tropical Storm Sonca will make landfall in central Vietnam on Tuesday night local time.

Flash flooding will be the main concern with areas from central Vietnam into northern Thailand at greatest risk.

There will also be a heighten risk for mudslides as rainfall of 75-150 mm (3-6 inches) falls across the region into Wednesday.

Typhoon Noru became the first typhoon of the season on Sunday. However, the storm is expected to remain well east of Japan this week with no impacts to land.
