July 12 (UPI) -- A major heat dome expanded from the interior West into the Upper Midwest on Sunday on its way to smothering the East later this week, forecasters said.
The heat in the East is expected to be shorter and less intense than the early July heat wave, but parts of the West are coming within a few degrees of all-time record highs.
Dangerous heat is also gripping even the Desert Southwest, where communities are used to extreme temperatures. The pattern will raise the risk of heat exhaustion, heatstroke and heat-related deaths.
Motorists are urged to carry plenty of water with them in the event of a breakdown.
