Isolated to scattered passing showers are expected through the
period, with a slightly higher chance tonight. Rainfall overall
looks to stay below average, and no major changes are expected in
the forecast. Because of that, confidence remains high that severe
weather is not expected. Easterly winds will stay light around 10
mph, while temperatures continue in the 90s.

Looking ahead to the weekend and into early next week, severe
weather is still not expected. Winds remain easterly around 10
mph, but may begin to decrease early next week as a trough
develops well to the south of the islands. Any showers that do
occur will likely be brief and passing. Temperature are expected
to remain above average.

Latest wave heights observed at the Aunu`u PacIOOS buoys remain
around 5 to 7 feet and is forecast to persist at these heights
through the new week. Although no significant swells or winds are
expected through the forecast period, wind speeds around 10 to 15
knots could produce textured seas at times. This means slightly choppy
conditions are possible, but not enough to warrant a small craft
advisory.
