| Area Forecast Discussion National Weather Service Melbourne FL 418am EDT Thu Mar 30 2023 Marine Issued at 205am EDT Thu Mar 30 2023 Today - Tonight Poor boating conditions will continue this period for the offshore/Gulf Stream waters as seas continue to build 4-6 ft here. Seas 3-5 ft near shore. Initial NE winds 10-15 kts will veer E/ESE tonight and increase to 15-20 kts over the Gulf Stream and up to 15 kts near shore. Friday-Monday...High pressure over the western Atlantic with the ridge axis extending southwestward across the local Atlantic waters shunted east-southeastward by an approaching cold front, which will weaken as it reaches the waters early Sunday. The front will then stall across or just south of the Treasure Coast waters, quickly losing definition, as high pressure builds back to the northeast again. Winds out of the southeast 15-20 kts across most of the waters Friday veer to southerly and briefly ease to 10-15 kts early Saturday, before increasing back to 15-20 kts late Saturday as the cold front approaches. By Sunday morning, winds have become northwesterly around 10 kts nearshore and 10-15 kts offshore, then continue to veer and weaken as the frontal boundary loses definition and weak high pressure begins to develop to the northeast. Winds become southeasterly and increase to 10-15 kts Monday as the high deepens. Seas 5-6 ft Friday subside through the day, becoming 3-5 ft by Saturday morning and 2-4 ft Sunday morning.
