Overview
- A persistent upper-level high-pressure dome over Minnesota is producing hot, dry conditions and heat-index values in the high 90s to triple digits with extreme-heat warnings in effect through Tuesday.
- Health officials warn that extreme heat can cause heat exhaustion, heat stroke and dehydration and can worsen chronic conditions such as heart disease, diabetes and asthma.
- The Minnesota Department of Health identifies pregnant people, older adults and very young children as the most vulnerable and urges them to stay cool, hydrated and out of midday sun.
- Counties and public libraries — including locations in Hennepin, Ramsey, Dakota, Washington and Anoka counties — are listed as cooling centers and officials are advising people to limit outdoor exertion.
- Meteorologists say the pattern shows little short-term relief, and forecasters link the event to a persistent upper-level high that fits into broader trends tied to El Niño and long-term warming, raising pressure on health and energy systems.
