Drought — Caswell, North Carolina

2023-12-01 to 2023-12-11 · Caswell, North Carolina

Event narrative

Severe Drought conditions already in place at the beginning of the month for all of Caswell County persisted until December 12th, when two low pressure systems passing across the lower Mid-Atlantic during the period of December 3rd to the 10th brought rainfall amounts ranging from 2.00 to 2.50 inches to the county. This precipitation resulted in a significant increase in soil moisture, surface stream flows, and ground water levels sufficient to allow drought conditions for the entire county to be improved to Moderate Drought per the U.S. Drought Monitor. Additional precipitation of nearly two inches on December 18th resulted in removal of drought for nearly all of the county, and further improvement to Abnormally Dry conditions through the remainder of the month. The precipitation moistened leaf litter and other fuels that support wildland fire activity, and a noted decrease in wildfires after these precipitation events was noted by the North Carolina Department of Forestry. There was no reported impacts to agriculture in December, with some farmers reporting that the lack of soggy ground make work in the fields easier to accomplish.

Wider weather episode

The passage of multiple low pressure systems near the Carolinas during the month of December brought abundant precipitation to northwest North Carolina, most of which fell as rain. Liquid precipitation totals varied generally from 4.5 inches to 6.5 inches for most of the northwest portion of the state, with a few totals reaching in excess of 9 inches along the crest of the Blue Ridge from Watauga County into Alleghany County. These precipitation totals were anywhere from 150 percent to over 200 percent of normal for December, making for vast improvements in local stream flows, ground water levels and soil moisture from their peak dryness in mid-November. As such, where Severe Drought conditions were in place across the entire northwest portion of the state at the beginning of the month, conditions improved to Moderate Drought by the end of December for areas along and west of the Blue Ridge, and to a combination of Moderate Drought and Abnormally Dry conditions across the foothills of the Blue Ridge and the Piedmont.
