KRLX radar — Charleston, WV

KRLX is the National Weather Service's WSR-88D Doppler radar for the Charleston area, operated with the NWS office RLX. View it live in TALON — the loop, super-res reflectivity, storm-relative velocity, rotation and correlation coefficient.

How high can KRLX see?

A radar beam travels in a nearly straight line while the Earth curves away underneath it, so the farther a storm is from KRLX, the higher above the ground the radar is looking. Tornadoes start in the lowest few thousand feet, so storms close to the radar show low-level rotation much better.

Severe weather inside KRLX's range

Since 1950, NOAA has recorded 91 tornadoes within 60 miles of the KRLX radar, 18 of them rated EF2/F2 or stronger. They have been most common in April and June. The strongest was an F5 on April 23, 1968, which passed about 44 miles northwest of the radar and caused 7 deaths. The most recent was an EF0 on May 26, 2024, which touched down about 18 miles north-northwest of the radar.

Hail: 947 reports of hail 1 inch or larger within 60 miles of the KRLX radar since 1955, 55 of them 2 inches or larger. The largest was 4.25-inch hail (softball size) on May 23, 2019.

KRLX radar FAQ

How often does KRLX update?

Every NEXRAD radar completes a full scan about every 4–6 minutes in storm mode, and repeats the lowest tilt more often (SAILS) during severe weather. TALON loads each new scan as it arrives.

What is the range of KRLX?

Reflectivity reaches about 290 miles and velocity about 185 miles, but useful low-level detail is within roughly 100 miles — see the table above.

Is KRLX down?

Radars occasionally go offline for maintenance. When one does, TALON's US radar map fills the gap from neighboring radars (KJKL, KFCX, KILN).
