Rounds of downpours from a strengthening tropical feature will increase the risk for flooding across the Philippines this week before tracking toward Vietnam.
The area of low pressure being monitored in the South China Sea developed into a tropical depression Monday evening, local time. The storm will remain largely stationary into the latter half of the week.
By Tuesday evening, the strengthened into a tropical storm and was given the name Nakri. In the Philippines the storm is know as Quiel.
Tropical moisture swirling around the storm will bring rounds of heavy rainfall to areas in the northwestern Philippines.
Areas that see multiple rounds of downpours throughout the week can expect rainfall totals of 100-200 mm (4-8 inches) with an AccuWeather Local StormMax™ of 300 mm (12 inches) possible, mainly in the higher elevations.
While the risk for flash flooding and mudslides will be high, damaging wind gusts are not expected to be a threat across the northwestern Philippines.
By the end of the week and into the weekend this feature is expected to begin to drift to the west. Residents of Vietnam will once again be under the threat of flooding rainfall.
Rain is expected to arrive across the south-central coast and southeast Vietnam by Saturday before spreading farther inland.
Widespread rainfall totals of 100-200 mm (4-8 inches) are forecast across parts of Vietnam, eastern Cambodia, eastern Thailand and southern Laos. Rainfall totals of 200-300 mm (8-12 inches) are expected in Vietnam near where the storm moves over land. An AccuWeather Local StormMax™ of 400 mm (16 inches) is possible across this area, especially into the mountains .
"This area was recently hit by Tropical Storm Matmo, so additional heavy rain from this budding tropical system could lead to new or renewed flooding," stated AccuWeather Senior Meteorologist Dave Houk.
Flooding rainfall will not be the only threat from this tropical feature. Wind gusts can reach up to 80-115 km/h (50-70 mph) in Vietnam near and just north of where the storm moves onshore.

Wind gusts of this speed can lead to minor damage, but due to the amount of rain the region has seen over the past week the saturated soil will make it easier for gusty winds to topple trees.
This is not the only tropical concern in the West Pacific basin.
Tropical Storm Halong developed to the east of the Mariana Islands on Saturday, local time. Halong then strengthened into a typhoon late in the day on Monday.
By Tuesday, the storm strengthened into a super typhoon to the east of the Mariana Islands.
Super Typhoon Halong is seen spinning over the open waters of the West Pacific on Tuesday, Nov. 5, 2019.
At this time, it appears that this system will likely only be of concern for shipping interests as it is expected to stay away from most landmasses.
AccuWeather meteorologists are also concerned that the warm waters east of the Philippines may also be conducive for tropical development late next week or the following weekend. This could spell more downpours for the already flood-weary country.
