The National Weather Service has issued a Flash Flood Watch that includes JSC and vicinity until 8AM CDT Wednesday.
As of 7:45 AM accumulated rainfall totals from yesterday to today around JSC ranges from: 3.15 inch at Bldg. 30, 3.36″ at Bldg. 421, 2.87″ at Nassau Bay to 0.85″ at NASA Ellington Field. Given the recent rains in the immediate JSC campus any additional heavy rain could cause some flooding issues as runoff will occur faster with saturated grounds.
A break in the rain is expected this morning but additional showers and storms are expected to develop between 11AM and 2PM north of JSC and move in during the afternoon hours.
