U.S. Braces for Record-Breaking Heatwave as El Niño and Drought Fuel Wildfires
Meteorologists warn that the U.S. is facing a tumultuous summer that could rank as one of the US’s hottest ever, with temperatures in the eastern states nearing all-time highs and wildfires intensifying across the West. More than 100 million Americans will be affected by this week’s heatwave, as El Niño and a severe drought amplify the risks of extreme weather.
El Niño and Drought Intensify Heat Risks
The current El Niño event, declared underway in June by the National Oceanic and Atmospheric Administration (Noaa), could be one of the strongest ever observed and is expected to boost global temperatures to new record highs over the next 12 to 18 months. This phenomenon, which releases stored heat from the Pacific Ocean, is exacerbating a drought affecting 45 states. In the West, low snowpack levels have raised concerns about wildfire risks, as noted by Guillaume Mauger, the state climatologist of Washington.
“Knowing what to expect early on gives people time to prepare,” Mauger said. “The ongoing drought and a strengthening El Niño will continue to tilt the odds toward unusually warm temperatures.”
Wildfires Threaten Air Quality and Infrastructure
Wildfires have already erupted in Colorado and other Western states, with smoke plumes reaching the midwest and eastern states. Firefighters are working to contain blazes amid water levels in the Colorado River that are on pace for new record lows, which have triggered new mandatory water restrictions affecting Nevada and Arizona.
“Our communities are feeling the firsthand impacts of severe drought and imminent fire danger,” Jared Polis said during a wildfire briefing. Smoke from Western fires has already led Minnesota, Wisconsin and Michigan to warn their residents about a heightened potential for unsafe air quality.
