Severe Storms with Flash Flooding Develop in NE

5 September, 19:00 UTC – We have watched strong, pulsating storms develop in the far NE, in the Suguiri and Mandiana Prefectures over the last hour. These storms have dropped over an inch of rain in an hour and are creating localized flooding. We have issued Dangerous Thunderstorms Alerts (shown as purple polygons below) for two storms in this region and others may develop.

We have watched these storms on PulseRad and the image below shows the location of the strongest storms.
