A Flood Watch remains in effect until 6 p.m. Thursday for all islands. An unstable and very moist air mass on the back side of the tropical system is lingering across the state. This moisture interacting with the land is expected to produce periods  of heavy rain and slow-moving downpours that could lead to flash flooding. If that occurs a more urgent Flood Advisory (flooding is imminent) or Flood Warning (flooding is occurring) will be posted by the National Weather Service.

Hilo side: Wave heights are expected to be knee/waist/chest high today. The best breaks open to the swell could get a bit bigger on the sets.

Kona side: Wave heights waist/chest high are expected for the best breaks open to the west blend swell. Could get up to shoulder/head high on the sets. Waist/belly high waves for spots that are catching the southerly swell.

South: Wave heights are expected to be knee/waist/chest high today for the best exposures open to the south swell. Spots open to the west will show in the waist/chest high range but most spots will be shut out.

Screen Shot 2015-08-26 at 7.52.54 PMOur current south-southeast, shifting south-southwest swell is expected to bump up a notch in size Thursday and Friday.

Kilo and Loke generated swell is expected to be fun size out of the west at about chest high through Thursday. Depending on how they develop we could continue to see swell from these.

Atsani has gone extra-tropical and we are expecting a west-northwest swell from Atsani to build Thursday and peak Friday.

Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
