* RUNOFF FROM INTENSE THUNDERSTORMS WILL QUICKLY FILL LOW LYING

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A FLOOD WATCH MEANS THERE IS A POTENTIAL FOR FLOODING BASED ON
CURRENT FORECASTS. YOU SHOULD MONITOR LATER FORECASTS AND BE
ALERT FOR POSSIBLE FLOOD WARNINGS. THOSE LIVING IN AREAS PRONE TO
FLOODING SHOULD BE PREPARED TO TAKE ACTION SHOULD FLOODING
DEVELOP. STAY TUNED TO WEATHER RADIO FOR FURTHER DETAILS OR
UPDATES

Let’s take a look at a couple of maps here to help explain the issuance of the Flood Watch…

The first map here shows the precipable water values. This is one indicator of how much moisture there is in the air. When you start to see the reds and yellows here on this map, the potential is there for very heavy rainfall. This particular model run is showing the values approaching two plus inches. That is where you can get very heavy rain. Also to add to the problem, the movement of the showers and thunderstorms today will be very slow. That will lead to training of showers and thunderstorms.

The projected radar image for early this evening shows plenty of shower and thunderstorm activity across northern and central Ohio this afternoon and evening. As stated earlier, the slow movement will lead to flooding issues in low-lying areas.
