Israel braces for unusual weekend storm as authorities warn of flooding, flash floods

The Israel Fire and Rescue Authority is on high alert ahead of an unusual rain event set to occur this weekend, with concerns over potential flooding and flash flooding. Following a Thursday assessment, Fire Commissioner Tafser Eyal Caspi has instructed all districts to increase readiness ahead of the storm, which is expected to peak overnight between Saturday and Sunday.

Wind gusts of 40-50 kph are anticipated as early as Saturday morning, followed by a significant weather change later in the day. The National Weather Service predicts an unusually severe rainstorm for this time of year, with the heaviest rainfall expected in regions such as the northern coast, Sharon region, greater Tel Aviv area, and the Shfela.

Up to 20-30 millimeters of rain could fall in coastal areas within a short period, accompanied by thunderstorms, lightning, and hail. Meteorologists warn of the possibility of urban flooding and disruptions in coastal cities. The Meteorological Service's Director, Dr. Amir Givati, described the system as unprecedented for this time of year, with some areas potentially experiencing double-digit rainfall amounts.

Eric Leibovitz, CEO of the Yarkon Drainage and Streams Authority, stated that starting Saturday night and lasting until Sunday morning, the area is under alert, with all necessary actions being taken. This event goes beyond a localized issue, signaling the need for intensive measures to prevent flooding. Ayalon Drainage, typically closed once every 10 years, may now be closed near once every three or four years due to reduced capacity and increased risk of flooding.

Leibovitz emphasized the danger of overflowing Ayalon and the inability of urban neighborhoods to contain the water, with failure points and bottlenecks in southern Tel Aviv exacerbating the issue. The rapid intensity of the rainfall could result in nearly 2,000 additional dunams being flooded, posing a significant threat to the region.
