URGENT - FIRE WEATHER MESSAGE
National Weather Service Brownsville TX
322 AM CDT Sun Apr 10 2022

...ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS LIKELY TODAY 
ALONG AND WEST OF THE I69C CORRIDOR...

.Relative humidity values will range from 20 to 30 percent across
much of the inland areas of Deep South Texas through this 
afternoon, with 40 to 60 percent along the lower Texas coast. As 
low pressure deepens across the Plains States, expect south to 
southeasterly winds to persist and remain gusty this afternoon 
and evening. Gusty southerly winds combined with low humidity 
between 20 to 40 percent will lead to the potential for elevated 
to critical fire weather conditions again today. Burning of any 
kind should be avoided.
