The concern for wildfires is high this weekend due to high winds and low relative humidity. Both of these factors were brought in partially due to a cold front that moved in this morning. Right behind that front is much drier air; so dry that relative humidity values this afternoon could be as low as 20%-30%.
We’re also caught between an area of high pressure to the west and Hurricane Matthew to the east, both of which are contributing to a northerly flow. Since the pressure difference between these two features is quite high, the winds between them, where we’re located, are quite strong. Winds Saturday afternoon will average from 10-15 mph with gusts up to 20-25 mph.
It doesn’t help that the Valley is falling deeper into a drought, so the ground and plants are dry as well.
The Red Flag Warning will be in effect from 1 p.m. – 6 p.m. for areas west of I-65 including the counties of Lauderdale, Colbert, Lawrence (AL), Limestone, Morgan, and Cullman. Burning should be avoided throughout the weekend.
