Calvin is tracking south of the big Island of Hawai’i this Wednesday morning (East Coast time, overnight in the Islands). Winds at the moment are below tropical storm strength, although on the higher ridge lines are probably higher. Rain bands are passing over most of the Islands; here are the 7am ET METARS and NWS radar composites, neither of which look too bad at the moment:
Here is the impact swath based on the 5am Central Pacific Hurricane Center forecast. The storm is currently just past the “3hr fcst” marker, which shows the position at 5am. Fortunately the storm shifted a bit south as it approached the islands.
Impacts are probably light unless something broke that shouldn’t, or the rain causes a flash flood or mudslide.
