Tornado + Flash Flood Emergency

06 Sep 2021 05:29 AM
The National Weather Service can place a special flag on both Tornado and Flash Flood Warnings to denote that they are emergency situations with an observed threat about to impact a populated location. A number of such emergencies were issued last week for post tropical storm Ida as it impacted the northeastern US. The Philadelphia NWS office had both a Tornado and Flash Flood Emergency active at the same time for Bucks County Pennsylvania. The featured table presents the IEM computed and unofficial instances whereby a given county was under a simultaneous Tornado and Flash Flood Emergency. The combination is very rare. The IEM has a page that lists out the emergency warning events.
