Nearly half the country is on alert for dangerous heat conditions, with meteorologists forecasting record high temperatures across broad regions. The extreme weather is producing distinct hazards depending on geography. In western states, hot and dry conditions are driving wildfires that have claimed lives. In the South, areas are recovering from flash flooding that killed at least four people, with conditions now shifting toward drier patterns. Weather forecasters are monitoring the heat wave's path and intensity across the country. NBC's Shaquille Brewster reported on the conditions affecting multiple regions, while TODAY meteorologist Al Roker tracked the forecast developments.
