Lowell is a Category 5. That sentence is not the same as “Kauai is in a hurricane.”
The Saffir-Simpson scale is maximum sustained wind. Category 5 starts at 157 mph. Lowell is at 160. It can weaken to a 3 or 4 and still wreck a coast. Iniki was a 4. Intensity is the engine. Track is whether the engine drives over your house.
Watch and warning, in English
A hurricane watch: hurricane conditions are possible in the area within 48 hours. That is when you finish the list — water, meds, documents, gas, a plan for pets and aunties. Kauai officials said watches could go up today.
A hurricane warning: those conditions are expected within 36 hours. That is when you stop debating the forecast cone and sit in the place you picked.
A tropical storm watch/warning is the same idea at lower wind. Coastal flood and high surf advisories are already up around Hawaii and Southern California. Those kill people who treat the ocean like a pool. They are not a consolation prize.
What “close pass” means
A center 150–190 miles west of Kauai can still throw south winds, 12-foot surf, and outer-band rain. Hawaii is built for northeast trades. South and southeast wind finds different roofs. KIUC already said outages may run Monday–Tuesday even on the current track.
Cone error on day four is still hundreds of miles. That is why Honolulu will not “declare this over.”
What this means for you
If you live in Kauai County, the watch — if it comes — is not panic. It is permission to be boring and ready. If you are watching from the mainland, do not confuse a Cat-5 headline with a landfall headline. Read the local emergency text codes, not a group chat.
Bottom line: 5 is the wind. Watch is 48 hours possible. Warning is 36 hours expected. The turn is Sunday. Act on the first word, not the last.
