Which radars cover Rio?

The closest NEXRAD Doppler radar is KMLB (Melbourne, FL), about 67 miles north-northwest. 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 Rio	View
KMLB Melbourne, FL	67 mi north-northwest	5,300 ft	Good — most storms and steady rain or snow show clearly
KAMX Miami, FL	111 mi south	11,300 ft	Limited — the beam overshoots the lowest part of storms
KTBW Tampa, FL	137 mi west-northwest	15,700 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.
