Important Takeaways:

  • Hone continues to weaken and is a strong tropical storm Monday after it blasted Hawaii’s Big Island as a Category 1 hurricane with flooding rain, damaging winds and dangerous waves over the weekend.
  • The Central Pacific Hurricane Center (CPHC) in Honolulu said the storm made its closest approach to the Hawaiian Islands on Sunday morning, passing about 45 miles south-southwest of South Point, Hawaii. Peak winds were estimated to be about 85 mph.

  • Flash Flood Warnings were issued through Sunday as heavy rain lashed the area, and forecasters estimated rainfall rates of 2 inches an hour.
