ALL / Austin, Travis County and South Central Texas Weather Update #2
Prepared by UT University/Incident Response Meteorologist Troy Kimmel
1050am CT – Friday / 09 September 2020

My Observations/Thoughts…
As I noted earlier today, given latest rainfall amounts, I am not concerned locally on the IH35 corridor at the current time with most ground truth rainfall in the immediate area generally less than an inch so far.. see map below..
My greatest immediate concern is for hill country well west/northwest of the IH35 corridor.
HOWEVER, please remember that there is more rainfall in the forecast with another couple of inches of rain possible; a Flash Flood WATCH remains in effect through tomorrow for the IH35 corridor counties and westward.. please remember, “Turn Around, Don’t Drown.”

Here are LCRA Hydromet rainfall amounts as of 1045am (since midnight)…
zzzzz

I’m continuing to monitor..
