#HeatPhotoContest feature: In this image, a 55-year-old cleaner wears a wide-brimmed hat to shade against the sunlight while wiping sweat from her face. Kyle Lam submitted this image to demonstrate how #heat can impact workers at their jobs.

#ExtremeHeat can damage crops, impacting food supplies and reducing farmer profits. This #HeatPhotoContest image from Miles Astray shows a field of damaged corn crops following two days of high heat. Check out more images from the contest: heat.gov/news/extreme-h…

#DYK? According to @CDCenvironment, fans can help keep you cool if temperatures are BELOW 90°F. But in temperatures above 90°F, a fan can actually increase body temperature. In this #HeatPhotoContest image by Alice Franchi, a group of people use handheld fans to stay cool.🪭

The heat will be on across the central U.S. for the middle of this week as a mid-level ridge shifts east. High temperatures will approach 90 from Texas to the Ohio Valley. This is about 30-40 degrees warmer than average for late March.

Not to sound like a broken record but... Over 200 new record high temperatures are forecast this week. 🥵 Record warmth will persist across portions of California, the Southwest U.S., the central Great Basin and will return to areas of the central/southern Plains and mid-lower Mississippi Valley later this week. Stay cool this week, check weather.gov.

Spring is here! As temperatures warm up, use this learning module from @NOAAeducation and NIHHIS as a resource to teach students about #HeatSafety. The module allows students to explore heat datasets through engaging, interactive lessons: bit.ly/4sdhOcm

A heat wave in the Western U.S. continues today with over 20 million people in the U.S. under heat advisories, watches, or warnings. For more information about staying safe before, during, and after heat events, visit Heat.gov. #HeatSafety

Early season #HeatDome persists over the western U.S., expanding east this weekend. Scores of daily record high temperatures are expected through next week with some additional monthly records for March through this weekend. Here are the updated Key Messages for this #HeatWave

An extreme early-season heat wave could see temperatures 20-30 degrees above average and record temperatures broken by 10 or more degrees today and tomorrow across the Desert Southwest. Jumping right into summer-like heat puts vulnerable populations at risk. Stay cool and check out weather.gov/safety/heat

Never, never, never leave children, disabled or elderly adults, or pets in parked, unattended vehicles! Studies have shown that the temperature inside a parked vehicle can rapidly rise to dangerous levels for people and pets. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies have not developed the ability to efficiently regulate internal temperature. weather.gov/safety/heat-ch…

This week’s heat from the West Coast to the Plains will set hundreds of daily records—many by several degrees. Some areas may even set March records, with temperatures more typical of June. Learn how to stay safe: weather.gov/heat
