Extreme fire danger will exist across much of western and central Texas, western and central Oklahoma and central and eastern New Mexico on Friday. The area outlined in red on the map above will experience the highest danger, which has been termed "critical" by the NWS.
Ground conditions across the region are extremely dry, due to a lack of significant moisture for much of the winter and first of this year:
Very (to extremely) low humidity, bone dry grasses and vegetation and gusty South-Southwest winds will create the perfect environment for rapidly spreading wildfires across the region on Friday.
All residents should avoid burning (it has been banned in most areas anyway) and promptly report even a small fire to authorities before it has a chance to get out of hand (which can be very rapidly in this type of situation).
