US: Tropical depression to bring flooding, high winds through Sep. 22
Tropical Depression 28W is forecast to bring 10-20 cm (4-8 in) rain, strong winds, and high surf to Northern Mariana Islands and Guam through the evening of September 22; flash flooding and transportation disruptions possible
Event
Tropical Depression 28W is forecast to bring dangerous storm conditions to Guam and the Northern Mariana Islands through the evening (local time) of Saturday, September 22, according to the US National Weather Service (NWS). As of 13:00 on Friday, September 21, the storm was located 162 km (100 mi) northwest of Guam and moving northwest. Despite moving away from the islands, it is expected to bring 10-20 cm (4-8 in) of rain and sustained winds of 46 km/h (29 mph) with gusts up to 65 km/h (40 mph). Waves as high as 3 m (10 ft) are also possible. The NWS warns that the islands remain heavily saturated from Typhoon Mangkhut's rainfall, raising the likelihood of flash flooding and associated transportation disruptions.
Context
Tropical cyclones and typhoons are common in the Pacific from June through November.
Advice
Individuals in the affected areas are advised to monitor local weather reports, adhere to instructions issued by local authorities, and anticipate transportation disruptions. Remember that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult.
