Which radars cover Gretna?

The closest NEXRAD Doppler radar is KLIX (New Orleans, LA), about 32 miles north-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 Gretna	View
KLIX New Orleans, LA	32 mi north-northeast	2,000 ft	Excellent — the lowest scan sees close to the ground
KHDC Hammond, LA	47 mi north-northwest	3,300 ft	Good — most storms and steady rain or snow show clearly
KMOB Mobile, AL	120 mi east-northeast	12,800 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.
