Public Information Statement

...EXTREME RAINFALL AMOUNTS FROM LANE OVER THE BIG ISLAND...

Rain bands associated with Lane have produced torrential rainfall

over the Big Island's slopes from Hawi on the north side of the

island to Naalehu on the south side. Significant flash flooding

has occurred in multiple areas across the northeast and east

facing slopes of the island. Several evacuations occurred, with

water rescues taking place at Kaiulani Street in Hilo and also

in the town of Keaau. As usual during heavy rainfall events, the

Bayfront area was inundated by the overflow of Alenaio Stream.

Highway 19 was closed in multiple locations due to landslides

and flooding. Akoni Pule Highway was closed by a landslide near

Halawa Gulch. Highway 130 was closed by flooding south of Keaau.

Numerous other roads were also closed by flooding.

Heavy rain and flash flooding also affected windward and southeast

sections of Maui, especially along the Hana Highway.
