Which radars cover Roche Harbor?

The closest NEXRAD Doppler radar is KATX (Seattle/Tacoma, WA), about 41 miles 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 Roche Harbor	View
KATX Seattle/Tacoma, WA	41 mi southeast	2,700 ft	Excellent — the lowest scan sees close to the ground
KLGX Langley Hill, WA	113 mi south-southwest	11,500 ft	Limited — the beam overshoots the lowest part of storms
KRTX Portland, OR	200 mi south	29,200 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.
