...Hazardous Boating and Beach Conditions Continue Today... Today - Tonight
Pressure gradient will continue to gradually relax as high pressure continues to build across the Southeast U.S. today. This will allow winds to decrease slightly today. However, north to northeast winds will still be breezy, especially along the coast, up to 15 to 20 mph. Winds will continue to weaken into tonight falling to 5 to 10 mph. Isolated to scattered onshore moving showers will continue to possible south of the Cape this morning. Then low end rain chances (20-30%) expand northward along the coast as an elevated E/NE low level flow may allow additional showers to develop over the coastal waters and push onshore into this afternoon and tonight. Highs will remain cooler than normal, ranging from the mid to upper 60s from Osceola/Brevard counties northward and in the low 70s across Okeechobee County and the Treasure Coast. It will not be as cold tonight due to a more onshore flow, with lows in the 50s, except upper 40s across Lake/inland Volusia counties.

Wave heigheights across the coastal waters will only slowly decrease today, with large breaking waves up to 7 to 9 feet still expected along area beaches. This will lead to very hazardous surf conditions, with strong rip currents expected throughout the day, and minor to moderate beach erosion continuing to be possible, especially during periods of high tide early this morning and again into this evening. A High Surf Advisory remains in effect for today and tonight, and a Rip Current Statement has been issued for today for a high risk of rip currents.

Sunday-Monday...High pressure over the Mid Atlantic coast will move offshore the SE states early in the week with light onshore winds and local continuation of an ongoing warming trend. Cool morning lows in the U40s to M50s Sunday will warm to the M-U70s with partly sunny skies. During Monday a similar pattern with flow becoming southerly will allow for some L80s to return with a little more afternoon clouds. A dry forecast continues.

Extended...Amplifying UA pattern over the plains will feature increasing moisture as sly flow increases Tue. Mentionable rain chances unfold over the northern area Tuesday as deep moisture combines with an approaching surface front to force more widespread precipitation coverage by Tuesday night and into Wed. A small chance of storms begins late Tue, with lingering rain chances and a storm mention continuing ahead of the approaching front Wed. Psg of the cold front by late Wednesday will bring a return to more winterlike lows, as longer range guid is suggesting of a return to L-M40s for a large part of the area Wednesday night and some 30s over at least the northern portion of the area on Thu night

Today - Tonight
N/NE winds around 20-25 knots this morning will decrease to 15-20 knots this afternoon. Winds will then veer to the E/NE tonight and continue to diminish to 10-15 knots north of Sebastian Inlet into tonight. Seas will be slower to subside, however, with seas up to 9-12 feet nearshore, and 13-16 feet offshore early this morning gradually falling to 7-9 feet nearshore and 10-12 feet offshore into tonight. Gale Warning has been allowed to expire, with a Small Craft Advisory now in effect for all of the coastal waters today into tonight for these continuing hazardous boating conditions.

Sunday-Monday...Winds will diminish further during Sunday, however lingering seas and swell will require a continuation of advisory and or caution stats into Sunday. The advisory should be trimmed to outer waters by Sunday afternoon. Monday will feature more favorable conditions, with a lingering swell over the open waters. flow will return to a Sly component by Monday afternoon and evening.

Extended...Winds will increase during Tuesday as next system approaches the region. Headlines will be likely for a portion of the waters by Tuesday evening mainly due to increasing winds. Showers and some storms will be possible as well into Wed, leading to locally higher winds and seas in areas of pcpn. Headlines will likely linger into mid week in post frontal wind surge.
