What was reported inside it

Time	Report	Where	Remark
Apr 7, 6:30 PM CDT	HEAVY RAIN 3.82	2 Sw Alexandria, LA	RAINFALL REPORTS FROM BROADCAST MEDIA IN ALEXANDRIA INDICATING 3.82 INCHES HAVE FALLEN ON THE SOUTHWEST SIDE OF THE CITY. ADDITIONAL REPORT OF JUST OVER 3 INCHES FROM WITHIN THE CITY CENTER.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Lake Charles Mun, LA (KLCH), launched 12:00Z, 10.2 hours before the alert went out and 148 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.
