A mid-level high pressure system holds fair weather over the
territory. Latest satellite data indicates cumulus clouds moving
along an east to west flow. Light winds currently observed at the
station is forecast to gradually increase tonight to 10 to 15 mph
as trade winds to the south extend over the territory. This
southeast wind is anticipated to persist throughout the new week,
intensifying to breezy conditions on Sunday as another high
pressure system builds to the south.
Meanwhile, a trough to the north will descend towards the Islands
on Monday. This feature will create a strong pressure gradient
with the high pressure system to the south. As a result, active
weather (strong winds and flash flooding conditions) is possible
through the end of the forecast period. However, our confidence is
low for forecasts greater than 3 days. Will continue to monitor
later trends and keep the public informed if active weather is
still expected for this duration.

Latest satellite data show wave heights have diminished to 6 to 8
feet as south swells subside. The high surf advisory was
cancelled this morning. Breezy winds expected later tonight will
continue the small craft advisory through the new week, possibly
extending as the high pressure system to the south strengthens
early in the new week.
