The North Carolina High Country, including Boone and Watauga County, is preparing for heavy rain and a considerable flood risk as the remnants of Hurricane Isaias move through the Carolinas. Gusty winds are also anticipated to accompany the system.
The most intense rainfall is expected to develop from late afternoon today and continue through early Sunday morning. While metropolitan areas may see 1 to 3 inches of rain, the mountains, particularly "favored upslope areas near the Blue Ridge Escarpment," could receive substantially higher totals, with 5 to 8 inches possible. These persistent downpours significantly increase the danger of flash flooding and landslides, especially in low-lying areas and locations with inadequate drainage. A Flood Watch has been issued for portions of the region.
Alongside the heavy rain, gusty winds combined with already saturated ground present a risk for trees to fall. Wind alerts are in place for parts of the mountains and foothills, prompting residents to exercise caution.
Beyond the primary threats of rain and wind, there is a low-end, highly conditional risk of an isolated severe storm and a brief tornado, especially along and south of I-85 and west of I-77. The precise timing and location of any severe weather remain uncertain, dependent on the speed at which a cool, stable layer of air east of the mountains erodes. This severe weather threat is forecast to shift eastward overnight into early Sunday morning, mainly east of I-77.
Looking ahead, Sunday is expected to begin with lingering showers and thunderstorms, with a rain chance of approximately 70 percent. However, conditions should gradually improve and become brighter by midday. Gusty northwest winds may continue over higher elevations into Sunday night and early Monday, with a slight chance of mountain showers early Monday. Charlotte temperatures are projected to rise from the 60s into the 70s on Sunday.
Following the storm's exit, sunshine is anticipated to return for the beginning of the week. High temperatures are forecast to be near 80 degrees on Monday, climbing into the mid-80s on Tuesday and Wednesday, before moderating to around 80 degrees on Thursday and Friday. The long-range outlook indicates a cooler trend for next weekend, with highs in the 70s and eventually nearing 70 degrees.
Residents are strongly advised to remain weather-aware throughout the storm. Essential safety guidelines include avoiding flooded roadways and never attempting to drive through water-covered roads, as conditions can be unexpectedly hazardous. It is also recommended to check current alerts for specific communities before undertaking any travel.
