Heavy Rainfall and Flooding Concerns in the Southwest; Coastal Low to Impact the East Coast

Deep tropical moisture will lead to widespread showers and thunderstorms capable of producing flash flooding through early next week over the Southwest and Four Corners. A coastal storm is expected to impact the southeast U.S. coast and mid-Atlantic regions with flooding, dangerous rip currents, gusty winds and heavy rain up much of the East Coast through early next week.

On August 20th our office sustained wind damage to the roof due to a 77 mph wind gust which hit the southwest corner of the building at 7:01 PM. The wind peeled back the outer layer of the roof allowing rainfall to pour through the remaining structure. There were no injuries to staff members, who responded immediately to the damage by calling backup sites and powering down electronics equipment to prevent water damage. The Des Moines forecast office assumed back up responsibilities immediately using our radar which was still in operation.

Amazingly enough all PCs and work station computers came up the next day. Our main casualty was the phone system. A replacement system, sent from our regional head quarters, was installed, configured and operational by the 22nd.

Estimated time for roof repairs is approximately one week.

Take a look at at the pictures. The first few shots are of the roof the evening of the damage along with a couple of sky shots showing mammatus clouds above our radar. There are also two interior shots which show workstations covered in plastic in anticipation of further rainfall. Note the missing and wet ceiling tiles where water poured into the operations area. The final few shots are of the patched roof on August 21st.
