NEW YORK (AP) — Residents of New York and New Jersey who were flooded out by Superstorm Sandy waited with dread Wednesday and heard warnings to evacuate for the second time in two weeks as another, weaker storm spun toward them and threatened to inundate their homes again or simply leave them shivering in the dark for even longer.

In New York, Mayor Michael Bloomberg ordered police to use their patrol car loudspeakers to warn vulnerable residents about evacuating, one of a number of measures that the beleaguered city was taking even as weather experts said Wednesday’s nor’easter could be weaker than expected.

“Even though it’s not anywhere near as strong as Sandy — nor strong enough, in normal times, for us to evacuate anybody — out of precaution and because of the changing physical circumstances, we are going to go to some small areas and ask those people to go to higher ground,” Bloomberg said Tuesday.
