Eastern Mediterranean: High temperatures forecast to persist in parts of the region through at least Aug. 15

Event

High temperatures are forecast across the Eastern Mediterranean through at least Aug. 15. The affected areas include Israel, Jordan, Lebanon, the Palestinian Territories, and Syria. As of early Aug. 11, the Israel Meteorological Service has issued orange heavy heat stress warnings for eastern Israel.

The Lebanon Meteorological Service has forecast a notable rise in temperatures from Aug. 12, especially in the highlands and indoors, where temperatures can exceed 40 C (104 F). A rise in humidity in coastal areas will increase the feeling of heat stress in these areas. Temperatures are likely to peak Aug. 13-14 before decreasing from Aug. 15. The service has warned of an increased risk of forest fires and advises people to avoid direct exposure to sunlight during the warmest periods of the day and to drink plenty of fluids.

The Jordanian Meteorological Department has warned residents to avoid direct exposure to sunlight at peak times, especially in the desert, Jordan Valley, Dead Sea, and Aqaba. Low visibility due to dust is possible in the desert. Officials could update and possibly extend the coverage of weather alerts over the coming days.

The high temperatures may result in increased energy and water demand and a heightened risk of heat-related illnesses, such as heat exhaustion and heat stroke.

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 speeds. 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 stress vehicles, 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.
