Beginning on October 15, various tropical cyclone warnings and watches were issued for Hawaii, starting with a tropical storm watch for the Big Island.
Three days later, a tropical storm warning was issued for Kauai and Niihau, and was extended to include portions of the Papahānaumokuākea Marine National Monument.
The threat of the storm forced parks and beaches to close in the state.
While passing south of Hawaii, Ana produced heavy rainfall on most of the islands, peaking at 11.67 in (296 mm) at Keaumo on the Big Island.
The rains caused the Sand Island water treatment plant in Honolulu to overflow, which sent about 5,000 gallons of partially treated wastewater into Honolulu Harbor.

Although no real-time wind reports of damage from Ana was reported on the Big Island, a post-storm report in November 2014 by resident Keith Robinson reported that there was damage in the southern vicinity of Niihau.
He reported extensive vegetation damage as well as tree tops levelled at "an estimated Beaufort Wind Scale range of 40–50 mph (64–80 km/h)".
Although it was not officially verified, the CPHC decided to treat the report as part of the conditions experienced in the area that was under a tropical storm warning.
