The September 15th Lake Effect Rain Flood

Lake effect rain occurs when the air temperature is much colder than the water temperature of a nearby lake. When the colder air passes over the warmer lake water, the air picks up some of the lake moisture and deposits it on areas downwind of the lake.

• On the evening of September 14th, 1996, the temperature of Lake Erie was 73 degrees.
• Overnight the lower atmosphere cooled into the upper 40s.

The forecasters knew a Lake Effect Rain event was going to happen, but they had to figure out where!

So they looked at the Doppler radar and saw the image below.

Your job (as acting meteorologist ) is to issue a flood warning for the location over land that received the greatest impact from the Lake Effect Rain Event Dave. On the radar image, click on the area that you think received the greatest rainfall.
