(CNN)- Severe weather is impacting multiple regions of the country as deadly flooding, extreme heat and wildfire threats continue to stretch emergency resources.

In Texas, heavy rainfall triggered widespread flooding Tuesday, forcing emergency crews to rescue at least 45 people from rising floodwaters. One truck was partially submerged after being swept away by high water.

Gov. Greg Abbott issued a disaster declaration for 59 counties as officials warned that some of the hardest-hit areas could see additional flooding in the coming days.

Meanwhile, California is facing a growing wildfire threat as temperatures climb and dry, windy conditions increase the risk of fast-moving fires.

Pacific Gas and Electric said it may implement proactive power shutoffs in parts of the Bay Area to reduce the risk of electrical equipment sparking new wildfires. The utility said the shutoffs are used only as a last resort during dangerous fire weather.

Wildfires are already burning in California, Colorado and Minnesota. Across the border in Canada, officials have ordered evacuations for several communities in northwestern Ontario as fires continue to spread.

At the same time, much of the United States remains under intense summer heat. Chicago recorded its hottest day of the year Tuesday, and forecasters expect numerous cities—including many along the East Coast—to see temperatures approach or break daily records in the coming days.
