The resources include weather safety information for people who are deaf and hard of hearing, warning signs of heat-related illness, summer infographics, checklists to stay safe before a heat wave, Spanish language outreach materials, heat safety social media resources, and social media graphics.

ALT Practice Heat Safety wherever you are. Job Sites: stay hydrated and take breaks in the shade as often as possible. Indoors: Check up on the elderly, sick and those without AC. Vehicles: Never leave kids or pets unattended - LOOK before you LOCK. Outdoors: Limit strenuous outdoor activities, find shade, and stay hydrated. Heat-related deaths are preventable. Protect yourself and others from the impacts of heat waves.

ALT Long-Duration Heat Wave Continues Sweltering heat persists over the central to southern U.S. through Friday night. Highs of 95-105°F, and limited nighttime relief due to numerous record warm lows in the mid-to-upper 70s°F, will maintain widespread Extreme HeatRisk from the Plains to the southern Mid-Atlantic. Heat Focus Shifts South This Weekend Relief from heat will arrive this weekend for the Ohio Valley and Mid-Atlantic, while dangerous heat lingers over the South-Central States through the holiday weekend into next week. Heat index values through the early next week are forecast to max into the 105-110°F range over the Southern Plains, Lower Mississippi Valley, and Gulf Coast. Protection from the Extreme Heat Limit afternoon outdoor activity, stay hydrated, and ensure access to A/C or cooling centers. Check on vulnerable family, friends, and neighbors. Ensure animals have fresh water and shade. Never leave kids or pets unattended in vehicles.

ALT Dangerous heat will persist across the Southwest through Friday with daytime highs of 110-115°F. Expect numerous daily record highs and Major to Extreme HeatRisk. Little overnight relief is expected as many areas may not cool below 80°F for several nights in a row. Temperatures return to near-normal levels over the weekend. Dangerous heat will build across the Southern Plains again beginning this weekend, and persist into next week. Daytime highs of 95-105°F, with limited recovery at night due to lows only in the mid-70s (°F), will result in widespread Major to Extreme HeatRisk. Increased chances for extreme heat continue into early Sep. A moderate risk (40-60% chance) of extreme heat remains highlighted across the south-central CONUS and Lower and Middle Mississippi, and Tennessee Valleys, Sep 4-6. Limit outdoor activity, stay hydrated, and ensure access to A/C or cooling centers. Check on vulnerable family, friends, and neighbors. Never leave kids or pets unattended in vehicles.

ALT Extreme Heat: Why is extreme heat so dangerous? Heat becomes especially dangerous if it lingers for more than one day. Hot days and warm nights don’t give our bodies time to cool down. Heat islands can intensify extreme hot weather, which can cause breathing problems, heat cramps, heat stroke, and may lead to illness or even death. What can you do? Check on your friends, family and neighbors during heat waves. Wear light, loose-fitting clothing and drink water often. Don't wait until you are thirsty. Avoid unnecessary hard work or activities if you are outside or in a building without air-conditioning. Stay in an air-conditioned area. Air conditioning is the strongest protective factor against heat-related illness.
