  • Flash Flood Watches for WV, western and northern VA, much of MD, DE, southern and eastern PA, NJ, southern NY, CT, RI, MA

Ida is not done with the U.S.

As of Tuesday evening, Tropical Depression Ida was 45 miles northwest of Knoxville TN, moving to the east-northeast at 20 mph. Maximum sustained winds are 30 mph. Ida’s rains will intensify over PA, southern NY and into southern New England Wednesday and Wednesday night.

Ida’s main threat is now flash flooding from increasingly heavy rains. Southern and eastern PA, northern NJ, southern NY, CT and RI could all see 4-7 inches of rain Wednesday and Wednesday night.

In addition to the rain and flood potential, there is a fair chance of tornadoes spinning up over MD, NJ, DE and extreme southeast PA (including Philadelphia). There will also be a band of 30-40 mph wind gusts Wednesday night moving across southeast PA, NJ into southern NY and southern New England.

Parts of PA, NY and southern New England could receive 1-2 months worth of rain on Wednesday and Wednesday night. If you can avoid traveling through this region tomorrow, I highly recommend you do so. Many roads, even major ones, will likely flood and become impassible.

If you are camping anywhere near a stream, lake or small river, pay particular attention to rising water levels and have a plan to move to higher ground before you are cut off.

As always, please follow the advice of local Emergency Management officials and stay alert for any Flash Flood Warnings or Flash Flood Emergencies issued for your location.
