Hurricane Madeline rapidly intensified from Sunday into Monday morning, and it may take a close swipe at parts of the Hawaiian Islands in the days ahead. Madeline's estimated peak surface winds increased from a 50 mph tropical storm Sunday morning, to a 125 mph Category 3 hurricane by Monday evening. A hurricane watch has been issued for Hawaii's Big Island. This means hurricane-force winds are possible within the warning area in the next 48 hours or less.

Comply with any evacuation orders issued for your area. If your
home is vulnerable to high winds... or you live in a surge zone or

possibility of significant wind damage... including downed trees
and power lines... and damage to roofs and weak structures.

... Storm surge and storm tide...
large and damaging surf is expected along east facing shores.
Surf will build today... and peak at 15 to 25 feet tonight through

to coastal properties and infrastructure... including roadways.
Powerful longshore and rip currents will be present at most
beaches. Large breaking waves and strong currents may impact
Harbor entrances and channels causing challenging boat handling.

flooding through late Thursday. Total rain accumulations of 5 to
10 inches are possible... with isolated maximum amounts near 15
inches... especially over windward portions of The Big Island. This
rainfall may lead to dangerous flash floods and mudslides. Refer
