6/18 – Trey Tonnessen’s “Humid Rain” Tuesday Night Forecast

Another lower end impact from PTC One will be elevated winds. These winds may be in excess of 20 mph in coastal areas because of the strong nearly zonal pressure gradient, so coastal flooding will continue to be a minor concern. The current coastal flood advisory was expanded to include areas around the tidal lakes based on current obs which show a 1 to 2 foot increase in lake levels today. Have held off on a wind advisory for now but will possibly need one for the south shore of Lake Pontchartrain at some point. Low temperatures will remain above the climatological normal for mid June due to the high moisture and remaining cloud cover.
