Severe Thunderstorms; Excessive Rainfall; Dangerous Heat; Air Quality Concerns and the Tropics

Smoky Mtn Observations

Isolated to scattered showers and thunderstorms, mainly during the late afternoon and early evening today, tomorrow, and Tuesday. Tuesday night will also feature a round of nighttime storms, with potentially severe wind gusts in the storms.

We are monitoring the potential for severe storms Tuesday night into Wednesday morning. The primary hazards will be localized flooding and damaging winds, but depending on whether or not a stable layer of air develops near the surface, a very low tornado risk cannot be ruled out. Stay tuned for updates!

Showers and storms are expected through this evening and again on Monday afternoon. A few strong storms are possible, with gusty winds and flooding the main threats. Cold front arrives sometime around Tuesday into Wednesday, bringing another round of showers and storms to the area, some of which could be strong to severe.

Each observation point is apart of our COOP program (Cooperative Observer Program). Each site has a 24 hour observation period that ends and begins at 8 am local time. Each site records temperature, precipitation, and snowfall data. More information about the COOP program can be found here www.nws.noaa.gov/om/coop/ Data began being collected at: Cades Cover on 01/01/1999 || Mount LeConte on 07/01/1987 || Newfound Gap on 01/01/1991 || Sugarlands Visitor Center on 12/01/1921
