The number of wildfires and acres burned were higher than normal in December and January, according to the S.C. Forestry Commission. As of Jan. 30, the Forestry Commission had responded to 200 wildfires that burned more than 531 acres. The number of fires in January was twice the five-year average, and the number of acres burned was 41% above the five-year average. Wildfire activity in the state typically peaks from February through April, as vegetation from the previous growing season was dormant and cured. The Sumter Item (S.C.), Jan 31, 2025

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0346 PM CST Fri Jan 31 2025 Valid 021200Z - 081200Z Upper-level flow will be primarily zonal across the U.S. to begin the extended period. Early next week, ridging aloft will increase across much of the U.S. east of the Divide ahead of a trough approaching the West Coast. Broad but moderate to strong cyclonic flow will then develop across the West into the Plains. Embedded shortwave troughs are also expected within the broader flow, but predictability of those features is low. At the surface, lee troughing in the southern High Plains will be a steady feature. Fuels will continue to dry in those areas under this regime. ...Southern High Plains... At least modestly dry and windy conditions are possible early to mid next week with the lee troughing expected. At present, wind speeds for much of that period appear too low to warrant any critical probabilities. By Wednesday into Thursday, deterministic and ensemble guidance suggest a deeper lee trough/low is possible in the region. Though the intensity of the surface winds will depend on the strength/timing of any shortwave trough feature, this pattern will favor an increase in dry and windy conditions in areas that will have increasing dry fuels by this point in time. The probability of critical fire weather is 40% on Wednesday afternoon. ..Wendt.. 01/31/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
