Millions of people across the United States are facing dangerous weather conditions as wildfires, severe storms, and an intense heatwave continue to affect large parts of the country.
Authorities issued multiple weather advisories on Tuesday as emergency crews battled rapidly spreading wildfires in California, while powerful storms triggered flood threats across the Midwest and unusually high temperatures gripped cities in the Northeast.
In Southern California, firefighters remained engaged in efforts to contain the growing Sandy Fire near the Simi Valley region and Burro Peak area.
The wildfire, which erupted on Monday morning, has already burned nearly 1,400 acres and was only 5% contained by Tuesday, according to fire officials.
Evacuation orders and warnings remained active across the region, affecting more than 10,000 homes as residents were urged to leave high-risk areas. Emergency services continued working to prevent the flames from reaching additional residential neighborhoods amid difficult weather conditions and dry vegetation.
Officials warned that shifting winds and extreme heat could further complicate firefighting operations in the coming days.
At the same time, parts of the Midwest experienced widespread thunderstorms and heavy rainfall that led to flash flooding in several communities.
Areas across Missouri and Illinois were among the hardest hit as torrential rain overwhelmed drainage systems and flooded roads.
According to weather authorities, more than 53 million people from southwestern Texas to northern Vermont remain under severe storm alerts.
Meteorologists warned of the possibility of damaging winds, large hail, additional flash flooding and isolated tornadoes as unstable weather conditions continue moving across the central and eastern United States.
Meanwhile, the northeastern part of the country is experiencing a rare and intense May heatwave.
Heat advisories affecting approximately 32 million people remain in place across a broad region that includes major cities such as New York City, Boston and Philadelphia.
Forecasters say temperatures in some areas are reaching record-breaking levels for this time of year, placing vulnerable populations at increased risk of heat-related illnesses.
New York City issued only its second-ever May heat advisory, an event described by meteorologists as highly unusual and another sign of increasingly volatile weather patterns across the country.
Public health officials urged residents to stay hydrated, avoid prolonged outdoor activity during peak afternoon temperatures and regularly check on elderly relatives and vulnerable neighbors.
The combination of extreme heat, wildfire conditions and severe storms has stretched emergency response systems across several states, with authorities warning that weather conditions could remain unstable throughout the week.
