URGENT - FIRE WEATHER MESSAGE
National Weather Service Austin/San Antonio TX
216 PM CDT Sun Mar 27 2022

...CRITICAL FIRE WEATHER CONDITIONS CONTINUE THROUGH MONDAY 
AFTERNOON...

Low relative humidities are expected through the rest of this 
afternoon, and again tomorrow afternoon. Minimum values in the low
20s and teens are expected along and west of US 77, with slightly
higher values to the east. South to southeast winds of 10-15 mph 
and locally higher gusts to 20-25 mph will be possible. This 
combination of dry air and moderate winds will mean near critical 
to critical fire weather conditions. Fuels remain unusually dry, 
and this is leading to an active season of wildfires that are 
difficult to contain. Any outdoor activity that could lead to the 
development of sparks and resulting wildfire potential is highly 
discouraged!

...CRITICAL FIRE WEATHER CONDITIONS CONTINUE THROUGH MONDAY
AFTERNOON...

Low relative humidities and gusty winds are expected again this 
afternoon. Minimum RH values in the low 20s to mid 30s are 
expected along and west of of I-35 and I-37 and in the mid to
