Which radars cover Gramercy?

The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 36 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 Gramercy	View
KHDC Hammond, LA	36 mi north-northeast	2,300 ft	Excellent — the lowest scan sees close to the ground
KLIX New Orleans, LA	55 mi east-northeast	4,100 ft	Good — most storms and steady rain or snow show clearly
KLCH Lake Charles, LA	151 mi west	18,300 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.
