I've linked the OFS page containing the current burn ban map below.

Currently, 60 of our 77 counties have burn bans in place. If you have any questions about the specific terms of the burn ban enacted by your county's commissioners, you can click on your county's name on the list below the map and read the text of your specific burn ban. If that doesn't clear up your questions, contact your local emergency management officials.

Many parts of Oklahoma are critically dry.

Please report all smoke and/or flames you see to your local 9-1-1 dispatcher, whether your county has a burn ban or not. Most areas of Oklahoma are critically dry and any grassfires that do start can morph into wildfires pretty quickly.
