The Spaceflight Meteorology Group has issued the following Special Weather Statement:
At 10:51 AM a thunderstorm was located over Ellington Field to about 2 miles west of JSC moving slowly eastward. As of 10:50 AM 0.68 inch of rain had fallen at NASA Ellington Field. As this storm continues to move slowly eastward expect 0.90 to 1.3 inches of rain at Ellington Field, SCTF and JSC in the next hour. Recent dry weather should mitigate the heavy rainfall but expect at least some minor nuisance street flooding onsite especially near construction areas. Rain may be a bit heavier on the north half of JSC.
