As an American, who has repeatedly lived thru snow storms, When I heard to weather forecast, I called my daughters in Israel on Tuesday and warned them. They did their shopping on Wednesday, did their laundry and cooked in advance.
they were ready, but even so, they lost power, at various times, lost their eruv and worried about power & heat on Shabbos. But they stayed home and stayed safe.
EVERYONE knew the storm was coming ! What fools left their errands for the night the storm was to start ?
Most Israeli’s I know, who are former Americans, did the same, parked their cars and hunkered down !!
