The remnants of Ida as a post-tropical low will move near Long Island late tonight into early Thursday. This approaching post-tropical low will allow for deep tropical moisture along the Middle Atlantic and Northeast to produce heavy rain showers this morning through early Thursday morning. The heaviest of the rain showers are expected late this afternoon through tonight. The rainfall should begin to taper off Thursday morning into the early afternoon from west to east. A widespread 3 to 6 inches of rain is forecast with locally higher amounts likely. This rainfall combined with wet antecedent conditions will likely lead to flash flooding. Flooding of fast responding rivers and streams is likely, with potential flooding of main stem rivers as well that could linger into the day Thursday.

PRECAUTIONARY/PREPAREDNESS ACTIONS
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. Stay away or be swept away. River banks and culverts can become unstable and unsafe.
