Returns tornado / severe thunderstorm / flash flood warnings within
radius_km, each with Impact-Based Warning tags (max hail size, max wind
gust, tornado detection / damage threat), parsed storm motion, expiration
times, polygon geometry, and whether the exact point is inside the
polygon. Watches in effect at the point are listed separately.

Downloads the latest RAP 13-km analysis profile and computes, with MetPy:
MLCAPE/MUCAPE/SBCAPE and CINs, LCL height, 0-1 and 0-6 km bulk shear,
0-1 and 0-3 km storm-relative helicity, Bunkers storm motion, effective
inflow layer, effective SRH/shear, supercell composite (SCP) and
significant-tornado parameter (STP). Interpretation reasons through the
parameter space like an analyst. First call may take several seconds.

Samples within radius_km: max 60-minute MESH (hail size, inches and mm),
max low-level and mid-level rotation-track azimuthal shear over the last
hour, max VIL, and max composite reflectivity — each with valid time and
the distance/bearing of the maximum from the point.

Normalized tornado, hail, wind, and flood reports within radius_km over
the past N hours: type, magnitude with units, time, location,
distance/bearing from the point, and remarks.

Runs warnings, SPC outlook, RAP environment, MRMS products, and storm
reports concurrently, then synthesizes: an overall threat level
(none/marginal/elevated/significant/extreme) with stated logic, hazards
ranked by concern, an environment summary, the nearest current storm
signature, and a recommended attention window. The first call can take
~10 seconds while the RAP profile downloads.

Metadata only (no imagery): radar site and distance, volume scan start
time, VCP (scan strategy) with meaning, max reflectivity and its
range/azimuth, and a coarse 18-dBZ echo-top estimate. Downloads a full
Level 2 volume (~5-15 MB), so expect a few seconds on first call.
