(CIRA/RAMMB) Now that Noul is inland and losing wind intensity, AccuWeather meteorologists expect flooding rainfall to be the predominant concern through the weekend.AccuWeather Meteorologist Tony Zartman explains, "Even though Noul will lose wind intensity and fall below tropical storm status, it will still pose a significant flooding threat into Sunday." Widespread rainfall totals of 100-150 mm (4-6 inches) are expected from this storm with 200-250 mm (8-10 inches) of rain in the mountainous terrain across central Vietnam, Laos, Thailand and southern Myanmar. An AccuWeather Local StormMax™ of 400 mm (16 inches) will be possible in the hardest-hit areas.The heaviest rain from Noul is expected to shift from Vietnam and Laos during the end of the week into Thailand and southern Myanmar through the weekend.This amount of rainfall as the storm tracks inland can lead to flooding and mudslides. Road closures are possible and some isolated communities could be inaccessible for several days.AccuWeather forecasters will continue to monitor Noul into the beginning of next week since what is left of the system after tracking over land is expected to emerge over the Bay of Bengal and can bring impacts to India next week.Keep checking back on AccuWeather.com and stay tuned to the AccuWeather Network on DirecTV, Frontier and Verizon Fios.
