...BEACH HAZARDS STATEMENT IN EFFECT THROUGH THIS EVENING...

The National Weather Service in Melbourne has issued a Beach
Hazards Statement for rough surf and a moderate risk of rip
currents, which is in effect through this evening.


* HAZARDS...Breezy onshore winds will produce rough surf and a
  moderate risk of rip currents today.

* TIMING...Through 9 PM.

* LOCATION...The surf zone and beaches in the central Florida 
  Atlantic waters from Flagler Beach to Jupiter Inlet. 

* POTENTIAL IMPACTS...Rough surf can knock you down and make you 
  even more susceptible to becoming caught in the seaward pull of 
  a rip current.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.

What forecasters said that day

The local office's own words before this beach hazards statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Melbourne, FL wrote its last area forecast discussion before this beach hazards statement went out at May 8, 9:35 PM EDT, 5 hours 45 minutes earlier.

Area forecast discussion, May 8, 9:35 PM EDT, 5 hours 45 minutes before
East Central Florida Forecast Discussion
National Weather Service Melbourne FL
935 PM EDT Wed May 8 2019

.DISCUSSION...
Currently...Steady state onshore flow out of the east will continue
overnight with beach and coastal winds keeping a mixed environment
at the immediate coast and lighter winds inland. There may be a
brief sprinkle from some of marine based SC as it comes ashore,
however measurable rain is not expected. The updated forecast
reduced rain chcs slightly for the overnight period given neutral
moisture advection and paucity of model indication of pcpn.

prev disc...

Tonight-Thu night...As tonight progresses, another area of high
pressure exiting the northeast US will merge with the aforementioned
high and remain over the mid-Atlantic coastal waters through Thu
night. Locally, the wind flow will remain from the east shifting a
bit from the ESE Thu night. As the edge of the ridge sits across
south FL, an area of higher surface moisture currently over the NW
Gulf will reach the FL peninsula on Thu. At the mid levels, high
vorticity will also accompany this area of weather and with a
descent easterly flow, development of afternoon showers and
thunderstorms is expected on Thu afternoon. However, these might
focus towards the western half of the peninsula, mainly affecting
the interior communities of Okeechobee, Osceola and Treasure Coast.
Highs are expected to reach the upper 80s-near 90 across the
interior and mid 80s along the coast.

&&

.AVIATION...
VFR conditions will prevail overnight and on Thu with easterly
winds, becoming light tonight and increasing to 10-15 kts after
Thu morning.

&&

.MARINE...
Tonight-Thu night...Thanks to the arrival of a northeast 10 second
swell, seas will build to 5-6 feet across the far offshore waters
east of Volusia and Brevard tonight through Thu night.
Operators of small craft should exercise caution. Winds will
generally be east 10-15 kts and southeast on Thu night.

&&

.MLB WATCHES/WARNINGS/ADVISORIES...
FL...None.
AM...None.
