Super Typhoon Bavi Makes Landfall on Pacific US Territories
The eye of Super Typhoon Bavi passed over the island of Rota on Monday morning local time, bringing winds of more than 150 mph. [3] Local authorities on Rota, part of the Northern Mariana Islands, say they have received reports of major damages. [3] The storm affected other parts of the Northern Mariana Islands and Guam, both US territories. [3] It was travelling at about 9 mph west towards the Philippines. [3] The NWS urged Rota’s residents on social media to treat these imminent extreme winds as if a tornado was approaching and move immediately to an interior room or shelter NOW. [3]
Flash Flooding Hits Guam and Rota
The National Weather Service in Tiyan has extended the Flash Flood Warning for Guam and Rota until 815 PM ChST.
