The Central Pacific Hurricane Center is tracking Tropical Storm Ana in the Central Pacific.
A flash flood warning is in effect for Oahu until 8 p.m. Sunday. At 4:45 p.m., radar showed moderate to heavy rain across most of Oahu. The rain was moving toward the north-northwest at 15 mph. Road closures have been reported along the southern portion of the island.
A tropical storm warning is in effect for Kauai, Niihau and Oahu leeward waters. A tropical storm watch is in effect for Kauai northwest and windward waters. A flash flood watch is also in effect for Maui County, Oahu and Kauai County.
At 3 p.m. Sunday, the center of Ana was located about 130 miles southwest of Lihue, Hawaii. Ana is moving toward the west near 8 mph. This motion is expected to continue through Monday, followed by a gradual turn toward the northwest Tuesday.
Maximum sustained winds are near 70 mph with higher gusts. Ana is expected to remain just below hurricane strength Sunday night through Tuesday, but is expected to remain a strong tropical storm.
Tropical storm force winds extend outward up to 105 miles from the center.
The estimated minimum central pressure is 29.35 inches.
Tropical storm conditions are expected over Kauai county Sunday, and over Nihoa Sunday night. Tropical storm conditions are expected over necker island, French Frigate Shoals, and tern island Monday night. Hurricane conditions are possible over French Frigate Shoals and tern island Monday night.
Large swells produced by Ana will continue to impact most of the main Hawaiian islands on Sunday, and will reach the northwest Hawaiian islands later Sunday and Sunday night. Surf produced by these swells could potentially be damaging along exposed southern and southeastern shorelines.
Ana is expected to bring total rainfall amounts of 3 to 6 inches, with local amounts up to 8 inches, over Kauai and Niihau. Rainfall associated with Ana will move over the smaller islands from Niihau to Maui on Sunday. Rainfall will gradually diminish later in the day over Oahu and Maui. Rainfall amounts of 4 to 8 inches, with local amounts of 12 inches, are possible over the northwest Hawaiian islands along and near the track of the center of Ana.
