Which radars cover Port St. John?

The closest NEXRAD Doppler radar is KMLB (Melbourne, FL), about 27 miles south-southeast. 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 Port St. John	View
KMLB Melbourne, FL	27 mi south-southeast	1,600 ft	Excellent — the lowest scan sees close to the ground
KTBW Tampa, FL	111 mi west-southwest	11,200 ft	Limited — the beam overshoots the lowest part of storms
KJAX Jacksonville, FL	149 mi north-northwest	17,900 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.
