Which radars cover Mandeville?

The closest NEXRAD Doppler radar is KLIX (New Orleans, LA), about 17 miles east. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.

Radar	Distance	Lowest beam over Mandeville	View
KLIX New Orleans, LA	17 mi east	900 ft	Excellent — the lowest scan sees close to the ground
KHDC Hammond, LA	21 mi west-northwest	1,200 ft	Excellent — the lowest scan sees close to the ground
KMOB Mobile, AL	113 mi east	11,500 ft	Limited — the beam overshoots the lowest part of storms

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
