Where the rain is now
NOAA composite radar, updating every couple of minutes — the most current thing on this page. Scrub back an hour to see which way the bands are moving.
Color is echo intensity, not rainfall reaching the ground — radar under-reads rain in the lee of high terrain, so the gulches can run hard while the map looks quiet.
What is active right now
Grouped by kind of hazard. A solid tag means conditions are expected; an outlined tag means possible; a dotted tag is an advisory or statement.
By island
Every Hawaiʻi forecast zone, grouped into the four counties. Open one to see each alert and who it covers.
County operations
Hawaiʻi County Civil Defense's own live data — shelters and road closures update themselves.
