State health workers will knock on doors across West Hawaii Island to check how ready people are for emergencies, a routine safety effort as a storm bears down on the islands.

• Health officials will go door to door in the Kona, Kohala and Hamakua districts starting the week of September 14.
• The visits are CASPER surveys, which measure how prepared each home is for a disaster.
• Answers are confidential, and staff will wear vests and carry ID so people can tell they are legitimate.
• The push comes as Hawaii tracks Lowell, with the storm's path still being updated.

Outlook: Expect the surveys to run through that week, with results shaping how the state targets emergency planning on the Big Island.
