The same "heat dome" weather pattern that had most of the country sweating through a days-long heat wave was sparking a new danger Sunday: severe storms.

Heavy winds in the Northeast had already downs trees and power lines Saturday, leaving one man dead in Vermont, according to the National Weather Service.

Another person was injured when a tree fell in a home in upstate New York, and a person in Massachusetts was injured when an awning blew off of a hotel, according to the NWS.

The storms would move west toward the Great Lakes and Midwest on Sunday, bringing torrential downpours that could cause flooding, according to Weather.com.

The pressure system causing the storms is the same system that had parts of more than 24 states still under heat warnings, advisories and watches, according to Weather.com.

A heat dome — a ridge of high pressure that traps hot air for an extended period of time — had lingered over some of these states since Thursday.

The Mid-Atlantic and Northeast was still suffering Sunday through heat indices — actual temperatures combined with humidity levels — of up to 110 degrees.

In the west, high temperatures of 97 degrees near Los Angeles were feeding a wildfire that had grown to 22,000 acres Sunday, according to the National Forest Service.

The heat wave is also especially dangerous because temperatures aren't dropping substantially at night, depriving people from any nocturnal relief, according to the National Oceanic and Atmospheric Administration.

So the National Weather Service recommends that people stay indoors (preferably with serious air conditioning), limit strenuous activities and stay hydrated to keep from overheating.

Many Americans would be wise to follow that advice until Tuesday when the heat wave is finally expected to break in some areas. But the Northeast, Mid-Atlantic and Carolinas likely won't see daytime temperatures plunge below the mid-nineties until Thursday, according to Weather.com.
