Hurricane Erin may bring isolated flash and urban flooding, landslides or mudslides, and possible tropical storm conditions to Puerto Rico and the U.S. Virgin Islands this weekend. Scattered thunderstorms and heavy rainfall may bring areas of flooding this weekend over the Upper Midwest. A tropical disturbance will bring locally heavy rain and mainly urban flash flooding to far southern Texas. Read More >
Overview
|
Two rounds of severe storms brought large hail, strong winds and brief heavy rainfall to portions of northeastern Wyoming and southwestern South Dakota. Storms began over the Black Hills in the afternoon hours, with large hail reported in Piedmont, Nemo, Black Hawk, Hart Ranch, and Hermosa. A second round of severe storms moved through in the evening hours as an upper level system combined with a cold front. These features allowed storms to develop in a line and move east through most of northeastern Wyoming and western South Dakota. Strong winds were associated with this line of storms with wind gusts exceeding 60 mph at Rochelle, near Dewey, in the Badlands, Cactus Flats, Cottonwood, Phillip, and Belvidere. |
