| Area Forecast Discussion National Weather Service Melbourne FL 228pm EDT Monday April 6 2026 ...New KEY MESSAGES,ARINE... .KEY MESSAGES... Issued at 211pm EDT Monday April 6 2026 - Excessive Rain Threat This Week: Multiple rounds of rain and storms are expected through Thursday, especially along the coast where totals of 2-5" are forecast. Localized higher amounts may lead to flash flooding in urban and poorly-drained areas. - Strong Wind Gusts Beginning Tuesday: Persistent northeast winds will gust from 25-35 mph starting Tuesday. There is a 20-40% chance of peak wind gusts exceeding 45 mph on Tuesday and Wednesday. These winds may cause a few power outages; secure all lightweight outdoor items. - Dangerous Surf & Boating Impacts: Large breaking waves building to 8-12 feet at Central Florida's Atlantic beaches Tuesday through Thursday, with higher waves offshore. Expect minor to moderate beach erosion around high tide and numerous life- threatening rip currents. Entering the ocean is strongly discouraged this week. Issued at 211pm EDT Monday April 6 2026 Current - Tonight The weak cold frontal boundary continues to settle southward across the central FL peninsula early this afternoon. Initial light northerly flow behind it will veer NNE/NE with speeds increasing to 10-15 mph, and perhaps 15-20 mph near/north of I-4 - highest along the Volusia coast, where gusts late today may approach 25-30 mph into this evening. This evening, much of the area south of Orlando will see winds diminish to 5-10 mph; whereas further north winds will stay elevated near 10 mph with higher gusts - esp along the Volusia coast (15-20 mph, gusts to 30 mph). Ahead of sunrise Tuesday morning here (Volusia coast), winds may pick up to sustained 20 to 25 mph with gusts 30+ mph. Expect cloud- cover to "thicken" thru the remainder of the afternoon and tonight, post-frontal. PWATs (Precipitable Waters) will surge to 1.50-1.75" nearly areawide thru late today. Weak troughing aloft develops over the Gulf as winds "back" to SW and pieces of shortwave energy push across the peninsula, esp evening/overnight with increasing upper support. SCT-NMRS convection remains forecast this afternoon and tonight. While we may see some initial activity develop along the ECSB, highest coverage over the interior during the late afternoon and early evening, then projected toward the coast during the night. Storm steering will be out of the southwest up to around 10 mph. A few strong storms are possible with main convective threats of lightning strikes, gusty winds to around 45 mph, small hail, and torrential downpours. The Weather Prediction Center (WPC) has placed pretty much ALL of ECFL in a Marginal Risk for Excessive Rainfall thru tonight. Therefore, some minor/nuisance flooding will be possible for locations that receive multiple rounds. Much of the area remains dry at present and can initially take some bouts of heavy rainfall. At the least, we are expecting some flooding of prone urban and poorly drained areas. Lows continue in the L-M60s for most. Tue-Thu...The former frontal boundary will settle across the southern peninsula/FL Straits thru this period. The Weather Prediction Center keeps much of ECFL within a Marginal Risk for excessive rainfall for Tuesday & Wed. General "troughiness" aloft will continue with numerous shortwave impulses traversing the central peninsula. Frictional convergence will be enhanced in the low- levels with the strong onshore flow. We are expecting slow-moving convergent convective bands to develop along the coast, with abnormally high coverage (60-80%) of showers and storms, esp for the climatologically driest month of the year for central FL. Multiple rounds of rainfall are expected thru mid-week and may promote a flooding threat. A Flood Watch may eventually be required, but much of the area begins this event rather dry so we will monitor conditions. At present, we continue to message peak amounts during this period of 2-4" along much of the coast, locally 5-7" in play here. For the interior, 1-3" and locally 4-5". Some areas may not receive these amounts and some could receive more, again much depending on surface/upper air features and where "banding" sets up with repeated rounds. While, this rainfall will certainly help bring some relief from ongoing drought conditions, too much rain too quickly could lead to (flash) flooding issues. With the proximity of the aforementioned frontal boundary, strengthening high pressure will push across the Atlantic Seaboard creating a tight pressure gradient across ECFL spreading southward during the day on Tue. This will increase onshore (NERLY) flow thru Thu, with windy/gusty conditions, esp along the (Volusia/Space) coast. Gusts approach 25-35+ mph on Tue/Wednesday (perhaps 40-45 mph Volusia/Space coasts). We will monitor for further Wind Advisory criteria. Breezy and gusty (G25-30 mph) onshore winds continue into Thu. Elevated winds & gusts will also continue each evening and overnight. This duration of strong onshore winds may cause sporadic power outages if limbs fall on power lines. Secure any lightweight items, such as trash cans, that may be tossed about. High coverage of clouds and precipitation will lead to below normal temperatures in the 70s Tue-Thu. Some areas north of I-4 on Tuesday may struggle to 70F or L70s. Overnight lows remain in the 60s. Strong onshore breezes will cause dangerous conditions along the coast, including rough, pounding surf and life-threatening rip currents persisting thru Thu. It is strongly advised to stay out of the ocean this week! Rapidly building surf spreading southward on Tue, with breakers reaching 8-12 ft by late Wed. Minor to moderate beach and dune erosion will be possible surrounding the twice-daily high tides beginning on Wed. Fri-Mon...Previous Slightly Modified...We should gradually come out of this impactful stretch of weather as we approach the weekend. Some lingering showers are still forecast on Fri (30-40%) and perhaps even Sat (15-20%) as fresh onshore breezes continue. Rainfall amounts should be lighter, however. Most locations should be dry by next Sun. A warming trend should get underway, with highs from the U70s to L80s. Lows consistent and in the L-M60s, save for some U60s at the coast. Marine Issued at 211pm EDT Monday April 6 2026 A weakening cold front settles across the local waters and remains in proximity thru mid-week. An abnormally high coverage of showers and storms will exist thru Wed-Thu. NERLY winds will also increase with building seas promoting hazardous to dangerous boating conditions for much of this week. Small Craft Advisories go into effect later today/tonight into Tue, with developing Gale conditions Tuesday afternoon thru at least Wednesday night. NE winds will reach 20-30kts sustained with occasional to frequent gust to Gale Force late Tuesday thru Wednesday night. Seas quickly build into Tue, 8-12 ft north & 5-7 ft south, continuing upward to 10-16 ft Tuesday night and Wed. Seas remain hazardous through the rest of the work-week as wind speeds only very gradually diminish.
