Records could keep falling throughout the country this weekend as AccuWeather forecasters warn of excessive heat reaching 90 and in some cases upwards of 100 degrees. Forecasters with The Weather Channel predict records could fall in the New England, the Great Lakes and the mid-Atlantic, where temperatures are expected to hit 100 degrees in some areas as the heat dome shifts over the Eastern U.S., trapping hot and dry air over an area for days.

Forecasters also believe excessive heat will also drive up the number of named tropical storms and hurricanes in the Atlantic this year. Last week, meteorologists at the National Oceanic and Atmospheric Administration predicted the upcoming 2024 season will bring a record 17 to 25 named storms, including up to 13 hurricanes, with four to seven of those intensifying into category 3 hurricanes (maximum sustained wind speeds of 111 mph or greater). If that prediction holds up, it would far outpace the yearly average of just over 14 named storms observed over the past 30 years, and potentially outnumber the busy 2023 season, which brought 19 named storms and seven hurricanes. The Atlantic hurricane season officially started on June 1.
