CONVERTING TRADITIONAL HAIL SIZE DESCRIPTIONS FROM THE NWS

Traditional object-to-size conversion for assessment and translation of severe hail reports.

We encourage measurement, not estimation, of hail size.

Do NOT run out into the falling hail during a storm

Wait until hail has stopped completely before going outside.
