Area Forecast Discussion National Weather Service Melbourne FL 409 PM EDT Mon Sep 11 2023 ...New MARINE, AVIATION... .DISCUSSION... ...High Risk of Dangerous Rip Currents Today... ...Marginal Risk for Severe Storms this Afternoon and Evening... Current-Tonight... Local WSR-88D imagery shows a few showers and storms along the east coast sea breeze as it pushes inland this afternoon, especially areas north of Sanford, and around Lake Okeechobee. This activity is moving very slowly, almost stationary, with convection dissipating shortly after the sea breeze pushes out ahead of it. A mid/upper level ridge remains in place, extending from the eastern GOMEX, across the Florida peninsula, to the Bahamas. At the same time, shortwave energy over the western/central GOMEX is slowly moving eastward through tonight. Locally, expect easterly flow to prevail at the surface, with speeds increasing to 10-12 mph behind the sea breeze. The east coast sea breeze has formed and is pushing inland this afternoon, sparking some convection along the boundary. Additional showers and storms are expected to form later this afternoon and into this evening. The highest potential for storms (PoP 40-50 percent) will be across the western interior as well as along the I-4 corridor, stopping just west of Daytona. The west and east coast sea breeze collision is expected to occur along the Lake/Polk county boarder later this afternoon. Otherwise, rain chances will be 20-30 percent. SPC has placed most of east central FLorida into a Marginal Risk for severe storms this afternoon. The 15Z XMR sounding continues to support this, with plenty of instability (MUCAPE over 3600 J/kg), sufficient shear (SFC-6km around 24 kt), cooler temperatures aloft (500mb temperatures around -7C), slight moistening in the mid levels, and PW values between 1.7-1.8". The stronger storms today will be capable of producing wind gusts of 40-45 mph, with isolated 50-60 mph possible, occasional to frequent lightning, torrential rainfall, and small hail. Any lingering storms today will dissipate before midnight, with mostly dry conditions overnight. A High Risk of dangerous rip currents remains along the central Florida Atlantic beaches this afternoon, and will remain through this week, as the outer swells from Hurricane Lee reach the local area. Entering the ocean is not recommended! Temperatures remain warm this afternoon, with plenty of sunshine. Temperatures as of 3 PM were in the upper 80s along the coast, and upper 80s to low 90s across the interior. Afternoon highs are forecast to be in the upper 80s to low 90s across the coast, and low to mid 90s across the interior. Peak heat indices this afternoon will range from 100-105F. Overnight lows will be in the low to mid 70s under partly cloudy skies. Tuesday-Friday... (Modified Previous Discussion) H50 high center over SOFL/Straits Tue morning erodes by Wed morning, replaced by westerly flow south of short wave troughs moving across the northern tier of the CONUS through late week. Hurricane Lee well east of FL will creep slowly WNW-NW through Wed before turning north a little east of 70W Thu, then picking up forward speed as it continues northward offshore the mid Atlantic/NE CONUS through Fri night. Of primary concern will be the dangerous conditions along the ECFL coast through the end of the work week. Expect large breaking waves building as high as 6 to 9 feet, along with a high risk of numerous strong rip currents. The rough surf and large breaking waves are expected to produce beach/dune erosion for several high tide cycles from Thu night into at least Sat morning. As such, a High Surf Advisory is looking increasingly likely during that time frame. Residents and visitors will want to stay out of the ocean during these dangerous conditions! Beachside residents should strongly consider taking action to protect vulnerable property from beach erosion, particularly in coastal Volusia County, which is still recovering from Hurricanes Ian and Nicole of 2022. Locally, the weak high pressure ridge extending from the SE US seaboard into central FL Tue-Wed collapses Wed night between peripheral NE flow around Lee to the east, and a weak frontal boundary sagging across the SE CONUS and the adjacent Atlantic. Freshening NE winds between departing Lee and a high pressure ridge building over the eastern CONUS will push the front S-SW into FL late Thu. The boundary will slowly sag across central FL Fri and into SOFL through Fri night. Sufficient moisture (PWATs 1.8"-1.9") will support scattered (40-50 PoP) diurnal convection Tue. PWAT values drop by a few tenths Wed, with PoPs dropping back to 20-30pct. As the front approaches and then sags into ECFL, even deeper moisture will spread across the region, leading to increasing PoPs both Thu (50 north-30 south) and Fri (50 far north/60-70 central-south). Given the freshening NE flow on Fri, coverage of TS should be lower compared to showers, with winds possibly becoming breezy along the Volusia/Brevard coasts Thu night-Fri. The threat for coastal showers will continue both Thu and Fri nights. Not much change to temps Tue-Thu...88-90F along the coast/L90s across the interior. Freshening NE winds coupled with increase in clouds/precip will hold down temps in the U80s, M80s along the coast from Cape Canaveral northward. Min Tue-Thu nights in the L-M70s areawide, with a bigger spread in mins Fri night... ranging from L70s west of I-95 to the U70s along the coast as onshore winds/warm shelf water hold temps up. Weekend... (Previous Discussion) Post-frontal high pressure over the eastern CONUS builds into the Atlantic, causing NE winds Sat to veer easterly Sun. With the frontal moisture band sagging across the southern half of the peninsula, drier air will filter into our northern counties, resulting in a N-S spread in PoPs both days. Tweaked NBM numbers toward this end, ranging from 20 north Lake/Volusia to 60 for Martin Sat, and from 30 NW of I-4 to 50 for the southern 3 cos Sun. Weekend max temps similar to Fri, mainly U80s except M80s for coastal Volusia. Mins Sat night ranging from 68-71F west of I-95 to M-U70s along the immediate coast, with more uniform L70s Sun night. && .MARINE... Issued at 401 PM EDT Mon Sep 11 2023 Current-Tonight... Current buoy 41009 observations show seas are 2ft with ENE winds around 4 KT. Seas will be 2-3ft in the nearshore waters, and building to 3-5ft in the offshore waters. ENE winds this afternoon will be 5-10 KT before becoming light and variable overnight. Isolated to scattered showers and storms will be possible later this afternoon and early evening, mainly in the offshore waters, as well as across the nearshore Volusia waters. Tuesday-Friday...(Modified Previous Discussion) Deteriorating boating conditions through the week due to building swells from Lee, coupled with freshening NE winds Fri. SCA will likely be needed beyond 20nm north of Sebastian Inlet by Wed as 4-6ft seas Tue night build up to 7-9ft by sunset Wed. Hazardous/SCA conditions spread south/shoreward Wed night onward with the current forecast showing peak seas 10-11ft well offshore Thu night/Fri morning. These values could get higher, depending on how large the swell train from Lee actually becomes. NE winds may approach 20kt from the Cape northward Fri, should speeds wind up closer to the GFS. && .AVIATION... (18Z TAFS) Issued at 401 PM EDT Mon Sep 11 2023 The east coast sea breeze has developed and has moved inland of the coastal terminals. Isolated VCTS across the interior terminals beginning around 20Z, and have added MVFR VIS/CIG TEMPOs (21Z/24Z) with this package. A storm or two could become strong to marginally severe with the ability to produce a quick downburst. Any developing activity will push back towards the coast during the late afternoon and evening with VCTS at DAB/TIX after 22Z. Convection will gradually diminish after sunset, generally clearing by 02Z. E winds around 7-10 kts prevailing though the afternoon. Light and variable winds overnight. && .PRELIMINARY POINT TEMPS/POPS...

Scattered lightning storms are forecast to develop after 3 PM through mid to late evening, primarily over interior portions of East Central Florida, including the Greater Orlando metro area. Stronger storms will be capable of producing wind gusts of 50 to 60 mph in isolated instances, occasional to frequent lightning strikes, and torrential rain fall of 1 to 3 inches, which could cause minor flooding in urban and poor drainage areas. Any lingering storms should diminish before midnight. .EXCESSIVE HEAT IMPACT... Afternoon heat index readings will peak at 100 to 105 across much of East Central Florida today. Seek time in the shade and take frequent water breaks while outdoors. If you are susceptible to high heat and humidity, stay indoors during the hottest part of the day. .RIP CURRENT IMPACT... There is a High Risk of numerous life-threatening rip currents today at all Atlantic beaches in Central Florida. Entering the ocean is strongly discouraged. Remember to heed all warnings from the beach patrol. .MARINE THUNDERSTORM GUST IMPACT... Over our inland lakes and coastal waterways, lightning storms this afternoon and evening will have the potential to produce wind gusts in excess of 35 knots, as well as frequent cloud-to- water lightning strikes. Mariners will need to watch the sky for rapidly developing and approaching showers and lightning storms. Gusty outflows from storms can arrive well ahead of the rain. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. Beach and surf conditions are forecast to become dangerous through this week. A High Risk of rip currents will persist at our Atlantic beaches, and increasing swells from distant Hurricane Lee will result in larger breaking waves of 5 to 7 feet by Wednesday evening through at least Friday or Saturday. At times of high tide, some beach erosion could begin to occur. Small craft operation will become hazardous in the open Atlantic waters and near inlets as seas build by the middle of this week. Scattered storms remain possible each afternoon and early evening. Frequent lightning, brief torrential rain, and gusty winds are the primary threats from these storms. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed this afternoon and tonight. Heil/Watson
