The most significant impact from Lester is expected to be very large and damaging surf along east facing shores.

WIND:
Wind conditions are expected to stay below tropical storm force (39 mph) for Hawaii County.

RAIN:
The majority of heavy damaging rain is expected to stay well to the north of the Big Island.

SURF:

A High Surf Advisory is posted through 6 p.m. Friday.

A High Surf Warning is posted from 6 p.m. Friday through Saturday at 6 p.m.

Very large and damaging surf, with peak waves of 20 to 35 feet, is expected along east facing shores Friday night into Saturday and diminishing on Sunday. These waves, in combination with a possible storm surge of 1 to 2 feet, may cause significant wave runup or damage 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 marine navigation.
