Unseasonal Winter Storm Brings Heavy Rain and Flood Risks to Northern and Central Israel

An unusual winter storm system is expected to hit Israel starting late Saturday night, bringing intermittent heavy rains primarily to the northern and central regions. The storm will be accompanied by strengthening winds and isolated thunderstorms, raising significant concerns about local urban flooding and flash floods in eastern riverbeds. According to the Israel Meteorological Service, rainfall will begin on Saturday evening, with the storm peaking overnight and into early Sunday morning.

This rare August weather event is caused by the intrusion of a cold air trough bringing unusually cold air masses at high altitudes, creating atmospheric instability when meeting the warm ground. This thermal turbulence is typical of early winter weather but highly uncommon for the summer month, which is usually dominated by a subtropical ridge that suppresses rain cloud formation.

The heaviest rainfall is forecast for the western and upper Galilee and the Golan Heights, where intense rains could lead to widespread flooding. Other parts of the country will see lighter rain, but strong gusts reaching up to 70 km/h may cause poor visibility and hazardous driving conditions. Authorities warn of serious flood risks in coastal plains and urban centers, especially where drainage systems are not prepared for such heavy rainfall at this time of year. Dry soil in eastern Israel also increases the risk of sudden flash floods in riverbeds.

Following the storm, temperatures are expected to drop significantly on Sunday, particularly in the mountains and inland areas, easing recent heatwaves. By midweek, conditions will improve with partly cloudy to clear skies and a gradual warming trend, returning to slightly above-average temperatures for the season in the highlands and hot conditions along the coastal plain.

Officials urge the public to prepare for the storm, avoid non-essential travel during peak rainfall, and exercise caution regarding flooding and flash floods. Continuous weather updates and adherence to safety instructions are strongly recommended.
