Israel, PT: Heatwave forecast to persist over much of the region through at least April 26

Forecast models indicate that high temperatures will impact Israel and the Palestinian Territories through at least April 26. Temperatures of 30-40 C (86-104 F) are expected across much of the region April 24-25, with isolated higher maximums. Temperatures are expected to drop April 26, although it will remain unseasonably warm in mountainous and inland areas. As of April 24, the Israel Meteorological Service has issued orange heavy heat stress warnings for Southern Golan, Lower Galilee, North Valleys, Western Galilee Slopes, Judean Foothills, Jordan Valley, Judea Desert Dead Sea, Eastern Negev, and Arava forecast areas. Orange elevated wildfire risk warnings are in place for Judea Mountains and Judean Desert Margins. Yellow strong wind warnings have been issued for Carmel Mt., Center Mountains, Northern Negev, and Negev Mountain; strong winds could generate dust storms in arid areas. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

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. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.

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 put more stress on vehicles, making tire blowouts more common. Major flight disruptions are unlikely at regional airports, 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.
