As of Thursday morning, EDT, Tropical Storm Damrey is centered in the South China Sea about 615 miles east-southeast of Da Nang, Vietnam; it is tracking towards the west at 13 mph.
Over the next 24 to 48 hours, Damrey will continue to move westward over the warm South China Sea and through an area of weak wind shear, promoting further organization and strengthening. Before reaching the south-central coast of Vietnam, it is has a chance to become a typhoon before making a likely landfall in south-central Vietnam either late on Friday or early on Saturday, local time. Main impacts will be flooding rainfall and damaging wind gusts during landfall.
Also, another area of tropical low pressure is centered near the southern tip of Vietnam. Land interaction now seems likely to preclude tropical cyclone formation, though locally heavy rain will be possible on the northern Malay Peninsula later in the week. We will continue to closely monitor this tropical weather system.

Tropical Storm Damrey will threaten Vietnam and Cambodia with flooding, mudslides and damaging winds late this week and into the weekend.
The cyclone was a tropical depression when it brought more than 300 mm (12 inches) of rain to parts of northern Visayas and southern Luzon earlier in the week. At least two people died in a landslide, according to The Manila Times.
The cyclone also caused disruption at several ports and resulted in several flights being canceled at Manila International Airport, according to the Philippine Star.
After crossing the Philippines, the depression strengthened into Tropical Storm Damrey on Wednesday, local time, as it emerged over the South China Sea. The cyclone is known as Ramil in the Philippines.
“This tropical system has the potential to become a typhoon before making landfall in southern Vietnam,” said AccuWeather Meteorologist Rob Richards.
Regardless of whether the cyclone is a tropical storm or typhoon, serious impacts are expected across southern Vietnam and much of Cambodia.
“Flooding rain, damaging winds and mudslides will be possible late Friday into Saturday, local time,” added Richards.
The most destructive winds would be near and just inland from where the storm makes landfall. At this time, areas from Vũng Tàu northward to Tuy Hòa are at highest risk for damaging winds.
Flooding rain and threat for mudslides will be a more widespread concern with areas from the north-central coast of Vietnam southward to Vũng Tàu at highest risk.
These areas can expect 150-300 mm (6-12 inches) of rain with local amounts over 400 mm (16 inches).
The threat for flooding and mudslides will extend into southern Laos and much of Cambodia where rainfall of 75-150 mm (3-6 inches) will occur.
The cyclone will weaken dramatically as it tracks over southern Vietnam and Cambodia, but could still produce some localized flooding across Thailand on Sunday and Monday as a tropical rainstorm.

Typhoon Damrey is expected to slam into southern Vietnam early this weekend. However, dangers to lives and property will also exist farther north in Vietnam, as well as in Laos and Cambodia. The tropical depression that triggered a deadly landslide and travel disruptions in the Philippines earlier this week strengthened into Typhoon Damrey over the South China Sea early Friday morning, local time. The cyclone is known as Ramil in the Philippines.

Landfall is expected near or between Nha Trang and Phan Rang-Tháp Chàm Friday night into Saturday morning, local time. Rain, wind and pounding seas will increase on Friday night across this part of southern Vietnam as Damrey approaches. The most destructive winds would be near and just inland from where Damrey moves onshore. Storm surge flooding will also further threaten lives and property near landfall and along the central coast of Vietnam.
"Damaging wind gusts of 145-160 km/h (90-100 mph) may occur closest to the center during landfall," said AccuWeather Meteorologist Rob Richards. Residents should be rushing to complete preparations, preparing for widespread wind damage, prolonged power outages and some structural damage. "After it makes landfall, Damrey will become more of a flooding threat," Richards said.

Flooding rain and threat for mudslides will be a more widespread concern with areas from the north-central coast of Vietnam and neighboring mountains of Laos southward to Bao Loc in Vietnam at highest risk. These areas can expect 150-300 mm (6-12 inches) of rain with local amounts over 400 mm (16 inches).
The heavy rain may linger the longest along the central Vietnam coast and into the mountains of Laos as moisture continues to stream onshore later this weekend. Another surge of moisture on the heels of Damrey may bring additional downpours to central and south-central Vietnam early next week, threatening to trigger more flooding and disrupt cleanup efforts. The threat for flooding and mudslides from Damrey will also extend across much of Cambodia as the weekend progresses where rainfall of 75-150 mm (3-6 inches) will occur. Sporadic wind damage may also result, especially across eastern Cambodia.
Damrey will weaken dramatically as it tracks over southern Vietnam and Cambodia, but the storm could still produce some localized flooding across southern Thailand later Sunday into Monday as a tropical rainstorm.
Before it become a tropical storm and was named Damrey, the cyclone unleashed more than 300 mm (12 inches) of rain to parts of northern Visayas and southern Luzon in the Philippines earlier in the week. At least two people died in a landslide, according to The Manila Times. The cyclone also caused disruption at several ports and resulted in several flights being canceled at Manila International Airport, according to the Philippine Star.

Het dodental als gevolg van de tyfoon Damrey in Vietnam is opgelopen tot ten minste 61. Er worden volgens de autoriteiten nog zeker 28 personen vermist. Door de overvloedige regenval dreigen enkele stuwdammen te bezwijken.
Tyfoon Damrey, de twaalfde zware tropische storm die Vietnam dit jaar trof, kwam zaterdag aan land. De storm ging gepaard met windsnelheden tot negentig kilometer per uur en beschadigde meer dan tachtigduizend huizen. Ook werden veel bomen ontworteld en viel in bepaalde gebieden de stroom uit.
De meeste slachtoffers vielen in de provincie Khánh Hòa, aan de Vietnamese kust. Volgens de hulpdiensten viel een deel van de doden op zee, nadat hun boten kapseisden. Er vielen ook slachtoffers door aardverschuivingen.
Volgens de autoriteiten in het land zijn meer dan dertigduizend mensen geëvacueerd vanwege de tyfoon. Ministers hebben voorafgaand aan een spoedzitting laten weten dat er mogelijk overtallig water moet worden afgevoerd om de druk op de stuwdammen te verlichten.
Vorige maand vielen door noodweer en overstromingen in het noorden en midden van Vietnam meer dan vijftig doden. De overstromingen in het land in Zuidoost-Azië zijn de ergste in jaren.
Vrijdag begint in Vietnam een top van het Aziatisch-Pacifisch economisch samenwerkingsverband APEC. Daarbij zullen ook de Chinese president Xi Jingping, de Russische president Vladimir Poetin en de Amerikaanse president Donald Trump aanwezig zijn. Er staat onder meer een bezoek aan de stad Hội An op het programma, die door de tyfoon op dit moment nog nauwelijks bereikbaar is.
