***NEW*** .. Flash Flood Warnings for Bastrop and Lee Counties Until 1245am …
.. Flash Flood Watch Continues for the IH35 Corridor Counties Until 1pm Thursday ..
.. Tornado Watch Continues for the IH35 Corridor Counties until 12 Midnight ..

.. Tropical Storm Bill.. Moving North Northwestward.. is Just South Southwest of Hallettsville …
.. Tropical Storm or Tropical Depression Still Forecast to Cross to the East of the Austin /
South Central Texas Area Late After Midnight Tonight into the Predawn Hours Wednesday ..
.. Heavy Rain and Slim Tornado Threat Areawide Along and East of IH35 Corridor — All Persons
in South Central Texas Should Remain Weather Through Daybreak Wednesday …

Rain bands are spreading west northwestward into the IH35 corridor counties as of 955pm on this
Tuesday. For the Austin metro area and the IH35 corridor counties, rain will become more continuous
with a few thunderstorms likely along with increasingly breezy/gusty northeasterly wind  as we make
our way through the night. As the center of Bill moves northward just to our east, we will see a small
risk of short lived tropical tornadoes along with the greater risk of flash flooding where heavier
torrential rains develop.

The latest guidance suggests that the system may stay just east of the IH35 corridor counties as
it moves north northwestward.

It’s important to note that the ground across the area from the IH35 corridor counties eastward
through southeast Texas (Houston area) is saturated or nearly saturated so additional rainfall that is
occurring in these areas is causing problems quickly. Those problems could.. and will likely in some
areas east of IH35..  grow to be very serious in a quick period of time!!

We must continue to be prepared through midnight and the predawn hours Wednesday. I urge you
to be “weather ready”.. have a plan.. and be ready to react to NWS/Austin-San Antonio short fused
weather warnings (flash flood and/or tornado) that may become necessary overnight. If you must be
out tonight in areas east of IH35, please remember the NWS slogan “turn around.. don’t drown.”

Please take this last opportunity.. before retiring for the night.. to please check your NOAA/NWS All
Hazards Weather Radios to make sure that the volume is turned up and that they are reset and ready
to be alarmed  if warnings are issued overnight into the predawn hours Wednesday.

Even after the center weakens and moves away from our area, additional rain is expected in the period
from tomorrow into Thursday that could continue cause flash flood problems.. thus the flash flood watch
being valid until 1pm  Thursday.

Continuing to monitor… next update by 7am tomorrow.
