Area Forecast Discussion
National Weather Service Jacksonville FL
1122 AM EDT Fri Sep 29 2017

...INCREASING NORTHEAST WINDS AND POTENTIAL FOR LOCALLY
HEAVY RAIN THIS WEEKEND AND EARLY NEXT WEEK...

.UPDATE...

Hot and humid again today with ample sunshine. Light and variable
flow will become easterly this afternoon. A quasi-stationary cold
front will remain just north of the Altamaha river basin today. A
coastal trough/tropical wave along the east coast of the Florida
peninsula will approach from the south this afternoon. A few
spotty showers will be possible inland this afternoon with the
seabreeze. Otherwise, there will be widely scattered showers and
possibly an isolated thunderstorm near the Altamaha river basin,
closer to the nearly stalled frontal boundary. Near record max
temps today with possibly a new record being set at Alma, GA,
where the record high of 91 degrees for this date was set just
last year.

The tropical wave/coastal trough will lift up the Florida
peninsula into our area tonight. Onshore flow will begin to
develop as the stalled front boundary gets pulled southward.
Low clouds will increase off the Atlantic towards sunrise Saturday
morning. Rain chances will also increase across our southern
coastal zones with the tropical wave late tonight.

&&

.AVIATION...
VFR today, then an increase in low clouds off of the Atlantic
ocean expected late tonight as onshore flow develops. In the next
TAF package (18Z), we will be adding low MVFR ceilings to all TAF
sites starting late tonight and continuing through Saturday. There
is some potential that these clouds could settle just below 1000
feet for a few hours early Saturday morning, but not confident
enough to forecast that just yet.

&&

.MARINE...
Light and variable winds will become easterly around 10 to 15 knots
this afternoon. Northeast wind surge will arrive on Saturday with
at least small craft advisory conditions expected by early
Saturday afternoon and continuing through the rest of the weekend.
We will wait until this afternoon before making the final
decision on whether to go with a small craft advisory or a gale
warning.

Rip Currents: High risk for northeast Florida beaches today.
Moderate risk for southeast Georgia beaches today. High risk for
all beaches this weekend as strong onshore flow develops with
increasing surf and rough conditions.

&&

.COASTAL IMPACTS...

Gages show that water levels on the St Johns River have subsided
enough for us to drop the Coastal Flood advisory. However, strong
onshore winds this weekend and the possibility of some heavy
rainfall in some areas will likely result in rising water levels
in the St Johns river and its tributaries by late this weekend
into early next week. The extent of these rises will depend on the
potential development and evolution of a low pressure system near
our coastal waters Saturday night into Sunday. Astronomical high
tides next week with an extended period of onshore flow will also
contribute to higher than normal water levels and some coastal
flooding will be possible next week. Additional coastal flood
advisories are likely.

...MODERATE TO HIGH RISK OF RIP CURRENTS...

...MINOR RIVER AND COASTAL FLOODING CONTINUES...

This Hazardous Weather Outlook is for Northeast Florida,
Southeast Georgia and the Adjacent Coastal Waters.

.DAY ONE...Today and Tonight...
There is a moderate risk of Rip Currents at southeast Georgia
beaches, and a high risk of Rip Currents at northeast Florida
beaches today.

Thunderstorms are possible this afternoon and evening. Locally
heavy rainfall is possible, but severe storms are not expected.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...
Local nor'easter conditions will develop this weekend and
continue at least through the middle of next week. Strong
northeast winds and building seas will produce dangerous boating
conditions, and combined with high astronomical tides, coastal
flooding and beach erosion will likely develop. Dangerous rip
currents are also expected. Locally heavy rainfall will also be
possible along the northeast Florida coast.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.

Jacksonville website on the internet at weather.gov/jax.
