Police say two highways are blocked in the south due to the adverse weather conditions.
Winter rains often cause dangerous flash flooding. It is unclear if the roads have flooded or if they have been shut due to concerns.
Route 90 is closed from the Arava junction to the Ein Gedi junction in both directions, and Route 31 is closed from Hatrurim intersection to the Neve Zohar intersection in both directions.
Drivers are asked to find alternative routes.
