Rains yesterday and overnight, ranging from near 8 inches in Galveston to 14 inches in Friendswood have exacerbated already disastrous flooding over Galveston and surrounding Counties and contributed to massive street flooding in Galveston this morning. Friendswood has received an incredible total of 49.12 inches of rain with Harvey, breaking the national record for precipitation in a single event.

With Harvey drifting slowly offshore about 90 miles east-southeast of Port O’Connor, we can expect more of the same today, probably creating a flood of epic proportions over much Southeast Texas. In addition, tropical storm force winds continue to rake Galveston and near coastal areas, with 47-mph wind gusts reported in Galveston early this morning.

Fortunately, high pressure building to the west is expected to finally nudge Harvey inland just east of Sabine Pass by Wednesday afternoon.

The good news about that is that is should lead to some sun and a decrease in precipitation by Thursday, In addition, this will result in gradually subsiding surge levels (which are currently running 2 ¾ to over 3 feet above normally expected levels) as winds swing around to the northwest and west in the wake of the storm: https://tidesonline.nos.noaa.gov/plotcomp.shtml?station_info=8771450+Galveston+Pier+21,+TX

An added benefit of receding tide levels on Thursday is that it will allow better drainage of rivers, bayous and streets. In other words, even this seemingly endless storm will pass out of our picture (weather-wise). Of course, we will all be dealing with the aftermath for some time to come.

Any idea what the total amount of rain Galveston Island has received during Harvey?

Right in the vicinity of 19 inches, counting rainfall after midnight until 9:10 am this morning.
