Austin / Travis County and South Central Texas Weather Update #7
Prepared by UT University/Incident Meteorologist Troy Kimmel
1107am CT – Saturday / 21 March 2015


.NWS/Austin-San Antonio Continues the Flash Flood Watch Until 7pm Today ..

.Quantitative Precipitation Forecasts (QPF)  Continue to Decrease the Amount
of Rainfall Expected Locally ..

Overall… according to latest QPF data sets.. predicted rainfall for the Austin metro area and
the IH35 corridor between now and early Sunday morning is now predicted at 1 1/2 inch or less.
I’m thinking it’ll be less than one inch in most areas.

The NWS/Austin-San Antonio  says it possible that some of the western parts of the current
Flash Flood Watch may be  dropped before the watch expires at 7pm tonight.

At 1100am this morning.. NWS Doppler weather radar shows light to occasionally moderate
rains continue over the area with the heaviest precipitation to the distant south through southeast
of the Austin area.

At 1100am this morning.. there are no flood problems in the area. According to www.atxfloods.com..
ten low water crossings (out of a total of 756 in the general area) have closed but these locations
are the ones affected first with any precipitation. Still, if you come up on these closed crossings,
remember, “Turn Around, Don’t Drown.”

As of 1100am this morning.. here are some representative area rainfall totals since early Friday…
Austin Great Hills NWS Coop Station…. 1.29″
Austin City (Camp Mabry) NWS ASOS…. 1.52″
Austin Bergstrom International Airport FAA ASOS…. 1.29″
Bull Creek at Loop 360 (LCRA)……………. 1.76″

All LCRA Hydromet totals, for the past 48 hours, in Travis and in surrounding counties are less
than 2 inches.

Light to moderate rainfall will continue across the area today into tonight with rain chances
diminishing after midnight tonight.

I’ll continue to monitor.
