Despite Haiyan weakening from when it hit the Philippines, we are still looking at some dangerous conditions the next few days over Vietnam, western Hainan and into southern China even.
Haiyan is continuing to weaken as it pushes closer and closer to another landfall in northern Vietnam. The system is in the South China Sea, and pushing northwestward. Winds with the storm are continuing to weaken, and as early as Sunday will weaken past typhoon strength.
Landfall of the storm is likely to occur just southeast of Hanoi, but despite weakening, the storm is likely to bring some heavy rainfall, localized flooding, mudslides and also stronger wind gusts. Landfall will occur late Sunday night, local time.
Rainfall over parts of northern Vietnam into southern China will be in the 10-20 cm (4-8 inch) range, and some areas may see over 30 cm (12 inches) with this storm as it weakens over southern China through Monday. This will likely cause some mudslides in far northern Vietnam and southern China.
The storm will continue to weaken, and AccuWeather.com Meteorologists believe this storm is now a Category 1 equivalent storm as of Sunday morning, local time. Though winds will gust to 95-110 kph (60-70 mph) at landfall in Vietnam, this is a far cry from what occurred in the Philippines with the first landfall.
Past storms for the area have brought heavy rainfall over the past few months, and that rainfall will only help to trigger dangerous mudslides and flooding with Haiyan moving through. The worst of the flooding is likely to occur near and east of the track of the storm. Even those on Hainan could see a few heavy bands of rain with the storm off to the west.
AccuWeather.com Meteorologist Erik Pindrock says, "Haiyan will bring northern Vietnam flooding rain and some damaging winds through the early part of the upcoming week; however, the extent of the damage should not be as destructive as when the former super typhoon ravaged the Philippines late last week."
