Clouds and showers will affect mainly windward and mauka areas, and may even reach the lee areas of the smaller islands at times. 21 Aug 2008 14:00:00 GMT http://www.prh.noaa.gov/hnl/pages/AFD.php#Synopsis http://www.prh.noaa.gov/hnl/pages/AFD.php Low clouds filled up nicely east of the islands overnight. Do expect some of these clouds to affect the islands in the coming hours, and will probably slowly burn off as the day progresses. Latest rainfall report continue to show light amounts across the state. Morning sounding from Lihue once again depicted a deeper low level moisture to about 9k feet, while it is lower to about 7k at Hilo. Hence there should be enough moisture for measurable precipitation. On the other hand, trade winds are strong enough to keep the showers moving, thus limiting the amount on any certain spots. High pressure north of the islands that is responsible for the trade winds is expected to persist through rest of the week into early next week. Forecast charts still indicate air mass to remain stable in the area, with no organized low level moisture expected. Rainfall totals will remain on the lower side, under the stable conditions with moderate winds. Forecast charts also indicate a slight increase with trade winds at times, though the overall weather pattern remains quite static, as the high north of the islands stays about the same strengthwise. On the other hand, there is a chance that trades do increase slightly by early next week, as moderate easterlies develop in the upper level of the atmosphere over the islands. Thus have continued with the previous forecast trend of slightly strengthening trades by early next week. In all, typical trade wind weather reigns, with passing clouds and showers affecting mainly windward and mauka sections, while a few may even reach the lee sections on the smaller islands. Big island lee areas will see afternoon and evening clouds and upslope showers, with clearing overnight into early morning. 21 Aug 2008 14:00:00 GMT http://www.prh.noaa.gov/hnl/pages/AFD.php#Discussion http://www.prh.noaa.gov/hnl/pages/AFD.php The few wind sensitive coastal waters and channels may see near small craft advisory level winds in the coming days, though still expect the conditions to be remained below the advisory level. No significant swell is expected, with some background slight southerly swell continuing. 21 Aug 2008 14:00:00 GMT http://www.prh.noaa.gov/hnl/pages/AFD.php#Marine http://www.prh.noaa.gov/hnl/pages/AFD.php None. 21 Aug 2008 14:00:00 GMT http://www.prh.noaa.gov/hnl/pages/AFD.php#HFO http://www.prh.noaa.gov/hnl/pages/AFD.php HUI 21 Aug 2008 14:00:00 GMT http://www.prh.noaa.gov/hnl/pages/AFD.php#footer
