Moderate to locally breezy trade winds will continue through the next few days with a gradual strengthening expected Thursday into Friday. Mostly dry conditions will continue to persist through Friday with some some passing showers over windward and mauka areas. As we head into the weekend, the main weather concern will be related to the tropical cyclone development of 93C, currently over 1000 miles east-southeast of the state. Residents and visitors should prepare now for potential tropical cyclone impacts this weekend. For the latest development regarding 93C, please check out www.hurricanes.gov.

Moderate to breezy trade winds are likely to remain in place through most of the week. Showers will focus over mostly windward and mountain areas, and remain light due to an area of drier air anticipated to move through the islands tonight through tomorrow.
No AIRMETs are in effect and none are anticipated.

High pressure to the far northeast will slowly drift into position north of the Hawaiian Islands into the weekend, producing moderate to locally strong trade winds across the region. A Small Craft Advisory (SCA) remains in effect through Wednesday afternoon for the windier waters and channels around Maui and the Big Island. The weather pattern may change significantly this weekend as we continue to watch for a developing tropical cyclone currently in an area roughly 950 NM east-southeast of the Hawaiian Islands. Potential impacts are uncertain at this time, as the tropical cyclone has not yet formed and track guidance remains highly uncertain at this time. Marine interests should be prepared in case this system potentially turns towards the Hawaiian Islands after formation potentially as early as this weekend.
Surf along south and west facing shores will continue to remain elevated as overlapping south swells continue to fill in around the islands through tonight. A moderate, long period south swell will fill in Wednesday peaking near or slightly above advisory levels late Wednesday into Thursday before slowly fading through the rest of the week.
Surf along east facing shores will continue to remain moderate and rough due to continued trade winds. Later in the week, the track of a developing tropical cyclone will dictate the potential for a large swell exceeding warning levels from the east to southeast direction.
Surf along north facing shores will remain flat to tiny through the week.
Due to a combination of peak monthly high tides and water levels running higher than predicted in a few locations, a Coastal Flood Statement remains in effect for minor coastal flooding around the afternoon high tide through Wednesday. Tides will be decreasing by the end of this week, but coastal flooding may continue to be possible around high tide for locations where water levels are running highest.
Small Craft Advisory until 6 PM HST Wednesday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Maalaea Bay-Pailolo Channel.
