Some areas could see up to 200 millimeters of rain, particularly along the northern coast and in the lowlands, prompting authorities to issue flood warnings and prepare emergency services for a severe weather event.

The storm follows Byron’s destructive passage through Greece and Cyprus, where it caused property damage, school closures, and travel disruptions, though no casualties were reported.

Rainfall is expected to begin on Israel’s northern coast on Tuesday evening with heavier showers expected along the coastal plain later in the night. On Wednesday, thunderstorms and heavy rain are forecast from the north down to the northern Negev, with flash floods possible in low-lying areas. By afternoon, precipitation will extend to the Negev and Dead Sea regions, increasing the risk of flash floods in desert streams.

The storm is expected to peak Wednesday night and Thursday, with particularly intense rainfall along the coast and in the lowlands, likely causing significant flooding. By late Thursday, flooding is expected to focus on the southern coastal plain, from Rishon Lezion to Ashkelon, while Dead Sea streams remain at high risk. Rain and flooding may continue into Friday, gradually tapering off during the day.
