Atlanta, Georgia, is bracing for a dangerous combination of extreme heat and thunderstorms on Thursday, July 17th, with high temperatures and heavy rain expected to impact residents and travelers.
With the heat index soaring between 100°F and 105°F, the city is on high alert, especially for those on major highways like I-75 and I-285.
Extreme Heat and Dangerous Conditions
Temperatures will climb into the low 90s, but it’s the heat index that will make the day particularly dangerous. Reaching between 100°F and 105°F, the heat can cause heat-related illnesses, especially for those outdoors.
The National Weather Service warns that these conditions will be even more intense for people who are commuting or engaging in outdoor activities. It’s critical to stay hydrated, avoid direct sun exposure, and take regular breaks in the shade or air-conditioned environments.
Thunderstorms Likely After 2 PM
Scattered thunderstorms are expected to develop after 2 p.m. on Thursday, bringing heavy rain, gusty winds, and the possibility of localized flooding. Motorists on I-75 and I-285 should be especially cautious, as visibility can drop quickly during the downpours.
Roads may become slick, and low-lying streets or underpasses could experience brief flooding, causing disruptions to travel.
Residents in areas like Fulton and DeKalb counties should prepare for stormy conditions throughout the afternoon and into the evening. As these storms roll through, there is a chance of minor disruptions, including power outages or tree damage due to gusty winds.
Weekend Outlook: More Storms Ahead
The unsettled weather continues into the weekend, with thunderstorms likely each afternoon. The risk of storms on Friday and Saturday is high, with a 40% chance of rain and storms after 2 p.m. Sunday will bring slightly less intense storm chances, around 30%, but it will still be hot, with temperatures reaching the mid-90s.
Residents should have indoor backup plans for outdoor activities during the weekend, as storms and high heat will make it difficult to enjoy outdoor events. As always, stay informed through local alerts to monitor changing weather conditions, and take steps to secure outdoor items that could be blown around by gusty winds.
What to Expect Next Week
The hot and stormy weather pattern is expected to persist into early next week. Thunderstorms are possible on both Monday and Tuesday, and temperatures will continue to hover around the mid-90s. Given the active weather pattern, additional warnings and alerts may be issued, so it’s essential to stay updated.
