US: Heatwave forecast to continue across much of Texas through at least June 15 /update 1
High temperatures forecast to continue across much of Texas through at least June 15. Transport and power disruptions possible.
Event
Excessive temperatures currently being experienced across much of Texas are expected to continue through at least June 15. Temperature records for the time of year are already being threatened across central parts of the state this week. The prolonged heat is expected to expand to cover most of the state and is expected to last through the middle of next week. Temperatures of 38-43 C (100-110 F) are likely across much of Texas over the coming days. As of early June 10, the National Weather Service (NWS) has issued heat advisories across portions of southeastern, south-central, and southwestern Texas.
High temperatures may result in increased energy and water demand and increase the risk of heat-related illnesses such as heat exhaustion and heat stroke. Authorities are advising the general public to avoid prolonged exposure to direct sunlight, wear loose and light clothing, and stay hydrated.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events.
Transport and Utilities
Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speed. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur as very high temperatures put more stress on engines, making tire blowouts more common. Major flight disruptions are unlikely, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
Advice
Monitor local media for weather updates and related advisories. During heat waves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating - drink bottled water or water that has been boiled. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur.
