Which radars cover Harahan?

The closest NEXRAD Doppler radar is KLIX (New Orleans, LA), about 36 miles northeast. 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 Harahan	View
KLIX New Orleans, LA	36 mi northeast	2,300 ft	Excellent — the lowest scan sees close to the ground
KHDC Hammond, LA	42 mi north-northwest	2,800 ft	Excellent — the lowest scan sees close to the ground
KMOB Mobile, AL	128 mi east-northeast	14,100 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.
