RH values are forecast to drop to 25-30% on Tuesday afternoon; however, winds should remain light enough to prevent a Red Flag warning. We will continue to monitor this in future updates. Fog potential over the next few days: There is a low chance (20%) of fog tonight along large bodies of water. Potential for Red Flag Conditions: None at this time; however, a low chance of increased fire danger exists in far NW AL on Tuesday afternoon where dry conditions, gusty winds, and dry fuels overlap.
