*** Impacts from Nicole together with very excessive rip present danger at NE Fl./SE Ga. space seashores by Fri… of us dwelling in or touring to the Bahamas, Florida & east coast of the U.S. ought to keep updated on the most recent forecasts *** ….
Probably the most anomalous (uncommon/uncommon) a part of this storm would be the potential for a comparatively robust tropical system at a moderately far north latitude for this late within the season along with a chronic interval – ~5 days of seaside/coastal impacts…
For Jacksonville/NE Fl./SE Ga. particularly (given *present* forecast of ‘Nicole’ with enhancing circumstances from west to east & south to north from Fri. afternoon by the weekend):
* Robust onshore movement will proceed & turn out to be even stronger by Thu. with life threatening rip currents & harmful total marine circumstances.
* Surf & breakers reaching double digits together with 12-15+ ft Thu., solely slowly subsiding Fri. Seas will likely be 20+ ft & extraordinarily tough simply offshore. All marine craft ought to stay in port & safe vessels & gear.
* Storm Surge (water above usually dry floor at excessive tide) will common 3-5 ft alongside the coast & the St. Johns River by a lot of d’city Jacksonville to close the Buckman Bridge… 2-4 ft south of the Buckman by St. Johns/Clay/Putnam Co. In case your property skilled flooding throughout Ian 6 weeks in the past or Irma (2017), then flooding might be going to happen in your space from Nicole. There could also be just a few spots the place storm surge reaches 6-7 ft over particularly Southern St. Johns & Flagler Co. the place seashores & dunes have been closely compromised by Ian. Surge values could also be domestically greater as a consequence of wave motion, heavy rainfall &/or geographical/topograhical nuances.
* St. Johns River – Probably important dock & shoreline injury by Fri. Robust winds from the south by late Thu./Thu. night time into Fri. morning will assist push water northward up the St. Johns River into components of downtown Jacksonville at instances.
* Seashore erosion will turn out to be heavy to extreme – a vital aspect of the storm contemplating the current injury from Ian
* Winds – BEACHES/INTRACOASTAL/ST. JOHNS RIVER – Tonight: rising to 20-35 mph with 40+ mph gusts… Thu.: peak at 40-50 mph with 60+ mph gusts changing into out of the south by late afternoon into the night time… Fri.: shifting to offshore – out of the west at 20-30 mph with greater gusts… a lot lighter winds by Fri. night time/Sat.
INLAND (NEAR/WEST OF I-95) – Tonight: 15-25 mph with 30+ mph gusts… Thu.: peak at 30-40 mph with just a few 50+ mph gusts… Fri.: shifting to out of the west then northwest by the day at 20-30 mph, greater gusts within the morning, regularly diminishing by the afternoon/night.
* Rainfall will common 2-3″(+) alongside the coast… 1-2″+ inland (close to/west of I-95)
* Flooding will likely be a day by day risk on the seashores, particularly at excessive tide – changing into extra important with every day by this week. There can even be an astronomical increase as a result of full moon section (every section of the moon is ~2 1/2 days in period) which started Tue. Ponding & – ultimately flooding – can even happen alongside the St. Johns River & its tributaries.
* As Nicole strikes south then west of Jacksonville whereas turning northward, there will likely be a twister & waterspout risk later Wed. night time by Thu. throughout NE Fl. & SE Ga.
* Major inland impacts are prone to be realized Wed. night time by Thursday within the type of wind, rain, flooding & tornadoes BUT WILL BE DEPENDENT ON EXACT TRACK & STRENGTH OF THE STORM.
Low strain – ‘98-L’ began to develop over the SW Atlantic north of Puerto Rico & was upgraded to subtropical storm “Nicole” early Mon., the 14th named storm of the Atlantic season which is correct on avg. & near the Nov. 19 avg. of the incidence of the 14th named storm. Nicole transitioned to a tropical storm (purely heat core) by noon Tue. & then reached hurricane (Cat. 1) power a bit earlier than 6pm Wed., the seventh hurricane of the Atlantic season which occurs to be proper on the seasonal common which – on avg. – happens on Nov. fifteenth. Given the very heat water from Fl. to the Bahamas along with an higher ridge constructing close to & north of the storm whereas – on the similar time – an higher degree trough that helped spawn Nicole weakens & strikes away, Nicole ought to handle to achieve hurricane power earlier than the Fl. landfall. Nicole has turned extra west & southwest & will veer extra west then northwest & because the ridge to the north briefly turns into stronger. On the similar time, one other higher trough strikes into the U.S. Decrease 48 serving to to create the alleyway from Fl. up the japanese seaboard because the temporary ridge shifts east over the Atlantic. This interaction helps to dictate the longer vary motion – acceleration to the north/northeast – in addition to aiding some within the power of Nicole by serving to to create robust higher degree outflow + enhancing the low degree “baroclinicity” – the interplay of chilly, dry, polar air vs. tropical heat & humidity. In different phrases, the transition again to a post-tropical low may imply a slower lower in Nicole’s depth despite the fact that Nicole will likely be shedding tropical traits & will not be over the nice and cozy ocean. Nicole ought to dissipate or turn out to be absorbed by one other midlatitude nontropical low over the weekend.
Typically, circumstances are not less than considerably favorable for added strengthening earlier than the Florida landfall. There’ll nonetheless be some shear + solely reasonable mid & higher degree moisture however sea floor temps. are heat together with fairly important deep oceanic warmth content material (heat water to a deep depth) to not point out Nicole will traverse the very heat Gulf Stream Wed. I’ve seen a number of instances during the last 20+ years that southwest shifting/digging tropical cyclones typically intensify.
World forecast fashions proceed to be in moderately outstanding settlement (for a storm in its infancy & not but effectively organized) with the low shifting west/southwest… hitting Southeast Florida… then as far west because the far Jap/NE Gulf or Fl. west coast to close the Jap Panhandle… earlier than feeling the results of the robust higher degree trough that can then lastly decide up the storm & steer it north & northeast whereas accelerating. The GFS stays the farthest west with Nicole. The European & UKMET fashions are comparable in power & take Nicole a little bit farther east earlier than a flip north/NE. All 3 fashions are comparable on timing. As I beforehand talked about, the approaching higher degree trough late within the week ought to assist to “ventilate” the mid & higher ranges of the ambiance over Nicole which ought to not less than keep the storm for an extended time than may in any other case be the case. As well as, rising southwesterly shear will likely be in tandem with Nicole’s motion lessening the impact of the rising shear of the entrance proper quadrant of the jet stream. As Nicole will get “captured” by the trough & hooks up with a chilly entrance, there will likely be a transition again to put up (non) – tropical that can then speed up the storm to the northeast shifting up the U.S. east coast by the weekend. Dry air will rapidly unfold eastward “below” – to the south – of Nicole’s middle bringing a fast finish to rainfall with diminishing winds & clearing skies for NE Fl./SE Ga. by late Fri./Fri. night time/Sat. In reality, the heaviest, most persistent rain for NE Fl. & SE Ga. ought to diminish by at leastThu. night time adopted by scattered showers & just a few t’storms Friday forward of an eastward shifting cool entrance extending south from Nicole.
The forecast is for Nicole to hurricane power between the Bahamas & Fl. ought to hit SE Fl./the east central coast as a Cat. 1 hurricane. Impacts are anticipated for all of Fl. – apart from the Western Panhandle & the Mid & Decrease Keys -… along with the Bahamas + components of the Carolina’s to maybe as far north as Chesapeake Bay & New England in the long term. Heavy rain will trigger potential flooding inland throughout Georgia, the Carolina’s, Tennessee, Virginia & Maryland & presumably components of the Northeast although the quick motion will preserve rainfall totals on the decrease facet.
REMEMBER: A thin forecast cone solely means greater forecasts confidence within the observe NOT the place the best impacts will happen. The wind area is large. In reality, tropical-storm-force winds prolong outward as much as 460 miles (740 km) particularly to the north of Nicole’s middle.

Spaghetti plots for Nicole – consists of ensemble fashions (NOAA: deal with underlying uncertainties within the enter knowledge such restricted protection, devices or observing programs biases, and the restrictions of the mannequin itself. GEFS quantifies these uncertainties by producing a number of forecasts, which in flip produce a variety of potential outcomes primarily based on variations or perturbations utilized to the information after it has been included into the mannequin. Every forecast compensates for a unique set of uncertainties):
Let’s do some “examinin’”:
Shear is at the moment robust throughout many of the SW Atlantic with speeds of 30+ mph. Nevertheless, the higher degree ambiance is present process some important modifications that can embrace considerably much less shear & a constructing higher degree ridge to the north of the low. On the similar time, a robust higher degree trough will likely be digging into the Central U.S. & ultimately into the Jap U.S. This robust trough will likely be vital to the eventual motion – together with curvature to the north/northeast – & depth of the storm. The added higher degree air flow from the trough might help in intensifying the storm some… or not less than sustaining the storm as it will definitely accelerates to the northeast. Following this trough, there will likely be a severe invasion of chilly air throughout the Decrease 48 because the tropical system appears to be a catalyst for a sample flip harking back to “Wilma” in 2005 which hit Fl. Oct. twenty fourth & was adopted/guided by a deep trough shifting throughout the Decrease 48.
Deep oceanic warmth content material (OHC) is fairly spectacular over the SW Atlantic although Nicole will typically keep north of the actual heat deep water (except for the Gulf Stream):

Water vapor loop exhibits pockets of dry air (darkish blue) throughout parts of the Atlantic Basin together with a number of “swirls” (low strain) together with “bands” of upper moisture close to & forward of fronts – widespread as we get deeper into autumn. ‘Nicole’ will likely be surrounded by a great deal of dry air this week.

Wind shear:
Saharan mud spreads west every year from Africa by the prevailing winds (from east to west over the Atlantic). Dry air – yellow/orange/purple/pink. Widespread mud is indicative of dry air that may impede the event of tropical cyclones. Nevertheless, generally “wanna’ be” waves will simply wait till they get to the opposite facet of – or away from – the plume then attempt to develop if different circumstances are favorable. In my private opinion, manner an excessive amount of is made concerning the presence of Saharan mud & the way it pertains to tropical cyclones. In any case, we’ve had a number of giant mud plumes unfold west to the Caribbean & Gulf with the height of Saharan mud usually in June & July.
2022 names….. “Owen” is the subsequent title on the Atlantic record (names are picked at random by the World Meteorological Group… repeat each 6 years). Historic storms are retired [Florence & Michael in ’18… Dorian in ’19 & Laura, Eta & Iota in ‘20 & Ida in ‘21]). In reality, this 12 months’s record of names is moderately notorious with “Charley”, “Frances”, “Jeanne” & “Ivan” retired from the ‘04 record (all hit Fl.) & “Matthew” was retired in 2016. The WMO determined – starting final 12 months – that the Greek alphabet will likely be not used & as a substitute there will likely be a supplemental record of names if the primary record is exhausted (has solely occurred thrice – 2005, 2020 & 2021). The naming of tropical cyclones started on a constant foundation in 1953. Extra on the historical past of naming tropical cyclones * right here *.
