Almost a half of the United States — a tract of land stretching from the Pacific Coast to the Great Plains and upper Midwest — is experiencing moderate to exceptional drought conditions, the National Oceanic and Atmospheric Administration said Thursday.

Why it matters: Conditions have prompted weather and agriculture officials to warn of water cutback in California, increased wildfires in the Southwest and damage to wheat crops around the country, according to AP.

  • NOAA said drought conditions, driven by La Niña and one of the driest monsoon seasons on record for the Southwest, are likely to worsen and expand, potentially affecting approximately 74 million people this spring.

What they're saying: "The Southwest U.S., which is already experiencing widespread severe to exceptional drought, will remain the hardest hit region in the U.S., and water supply will continue to be a concern this spring in these drought-affected areas," said Mary Erickson, deputy director of the National Weather Service.

By the numbers: Currently, 66% of the U.S. is under abnormally dry conditions, 44% in moderate drought and almost 18% is in extreme drought, the National Drought Monitor showed Thursday.

The big picture: The National Interagency Fire Center said in its significant wildland fire potential outlook for March that background drought will create above normal significant fire potential this spring for the Southwest, southern Plains and Northern Rockies region.
