Practice HEAT SAFETY Wherever You Are. Heat related deaths are preventable. Protect yourself and others from the impacts of heat waves. 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. weather.gov/heat
Afternoon WBGT values are forecasted to range from 84-92 degrees over the next few days. Extreme values of 90 or more will occur in some locations between 1-4 pm.
Heat stress is commonly measured by the Heat Index or the “feels like temperature”. An alternative method is the wet bulb globe temperature (WBGT). WBGT estimates the effect of temperature, relative humidity, wind speed, and solar radiation on humans. WBGT is derived from a combination of temperatures from three thermometers: Black globe - for solar factor (sun angle and cloud cover), Wet bulb - for humidity, and Dry bulb - for the ambient temperature. WBGT values of 90 or greater are dangerous for strenuous outdoor activities. https://www.youtube.com/watch?v=jstHHkm_6vQ
Hot and humid conditions continue with high temperatures mostly in the 90s to triple digits. Max Heat indices are expected to reach 100-113 degrees. Near zero rain chances, though there is a possibility of isolated showers along the sea breeze this weekend. Please practice heat safety by checking on the elderly, children, and pets, staying cool and hydrated, and wearing light-weight, light-colored clothing.
