Coastal Flood Advisory This Weekend in Sunny Isles Beach: Josephine Did Not Trigger a Hurricane Deductible

Friday morning, October 23, two products that looked related on a phone are not the same file. The National Hurricane Center’s 8 a.m. EDT Tropical Weather Outlook from Forecaster Beven has no tropical cyclone in the Atlantic, the Caribbean, or the Gulf of America, and it does not expect formation during the next seven days. Josephine already used the name. National Weather Service Miami’s 12:36 a.m. EDT coastal hazard message upgraded Coastal Miami-Dade — including Sunny Isles Beach and Haulover — from this week’s Coastal Flood Statement to a Coastal Flood Advisory until 8 p.m. Saturday, with moderate flooding of lots, parks, and roads.

That advisory is the shopping-advice change the October 19 deductible-trigger guide reserved. A 40% outlook was not a new article. A Miami-Dade coastal-flood advisory is. Josephine was named at 5 p.m. AST October 21 as Subtropical Storm Josephine, Advisory 1, about 265 miles south of Nantucket, with 65 mph winds and no coastal watches or warnings. The last National Hurricane Center advisory, number 5 at 5 p.m. AST October 22, listed a post-tropical cyclone 235 miles east-southeast of Nantucket, still with no coastal watches, then handed the system to High Seas Forecasts. Florida never posted a Josephine watch. A hurricane deductible did not start.

Keep the lanes. This page is not a rewrite of how wind, storm surge, and flood split on an HO-3. It is not the September 21 king-tide auto comprehensive guide. It is not the September 18 NFIP versus private shopping worksheet. It is not Tuesday’s October 20 takeout calendar. A named storm off Massachusetts, a Coastal Flood Advisory on Collins Avenue, and a king-tide peak on Tuesday are three different products.

Josephine Closed as a Subtropical Storm Off New England

The National Hurricane Center’s 2026 North Atlantic summary as of 09 UTC October 23 lists ten named storms, one hurricane, and one major hurricane. Accumulated cyclone energy sits at 19.5 — 82 percent below the 1991–2020 normal. Direct deaths and U.S. damage in that preliminary table are still listed as zero. Isaias (October 6–10, peak 105 kt / 959 mb) remains the only hurricane. Josephine is storm 10: a subtropical storm, October 21–22, 55 kt / 988 mb, 1.5 ACE. The archive labels it Subtropical Storm Josephine, not a hurricane.

Advisory 1 was already a northeast track away from the United States. Advisory 5 put the center near 40.0°N, 65.8°W, moving northeast at 17 mph, with a turn east south of Nova Scotia and Newfoundland. NHC said Josephine had become an extratropical cyclone and could reach hurricane-force winds as that extra-tropical low. Extra- tropical hurricane-force winds off New England are not Florida Statute 627.4025. The statute still needs an NHC-declared hurricane and a hurricane warning for some part of Florida. Neither happened for Josephine. The October 19 how-to already covers named-storm deductibles, surplus-lines menus, and the calendar-year credit from Isaias. Do not reread it as if this morning’s advisory reopened that clock.

A named-storm deductible on a surplus-lines form can apply to an NHC-named subtropical cyclone. Josephine was named. That still does not put Tuesday’s king-tide water on that line. The loss has to be caused by that storm at this location. NHC’s own last advisory put Josephine’s land hazards on the northeastern United States and the Mid-Atlantic, with large swells along the eastern seaboard. National Weather Service Miami’s Area Forecast Discussion at 7:53 a.m. EDT October 23 ties this weekend’s rain, northeasterly gusts, and moderate-to- major coastal flooding to a mid-level Atlantic trough or cutoff low and onshore flow over king tides — not to a center 235 miles east-southeast of Nantucket. A soaked Collins Avenue garage is still flood. A soaked car is still comprehensive.

The Local Product Upgraded: Statement to Advisory

Tuesday night’s 9:52 p.m. EDT October 20 coastal hazard message kept Coastal Miami-Dade on a Coastal Flood Statement — isolated minor flooding around high tide. Overnight, NWS Miami continued a Coastal Flood Advisory (CF.Y) for Coastal Miami-Dade and Coastal Broward until 8 p.m. EDT Saturday. The text is specific: moderate coastal flooding; flooding of lots, parks, and roads with only isolated road closures expected; take the necessary actions to protect flood-prone property; do not drive around barricades or through water of unknown depth.

Offshore, NWS Miami’s 12:39 a.m. EDT marine message keeps a Small Craft Advisory for coastal waters from Deerfield Beach to Ocean Reef out 20 nautical miles until 8 p.m. Sunday, with northeast winds 15 to 25 knots and seas 4 to 7 feet building to 10 to 15 feet on Sunday. Biscayne Bay adds a Small Craft Advisory from 5 p.m. today through 11 p.m. Saturday. A small-craft advisory is not a tropical-storm watch. Citizens’ bind rule — agents may not bind new or increased coverage when a tropical-storm or hurricane watch or warning is posted for any part of Florida — is not tripped by an advisory, a rip-current statement, or rough bay water. The October 10 lift after Isaias is still the last bind bulletin.

Tuesday Is Still the East-Coast Annual Peak

Miami-Dade Emergency/Risk Management’s king-tide calendar still lists October 24–30 as the highest predicted window, then November 6–9 and November 23–26. The South Florida Water Management District’s east-coast window of October 22–November 12 still has the annual peak on October 27. National Weather Service Miami’s own coastal product now puts that peak against rain and onshore winds, not against a quiet astronomical tide.

NOAA Station 8723080 at Haulover Pier, datum MLLW, is the public gauge for this barrier island. Official predictions as of this morning:

Those are predicted astronomical tides. Onshore wind, rain on already-high water, and wave run-up are why NWS Miami is talking about a possible warning Sunday and Monday — not because Josephine is still a subtropical storm. County king-tide guidance is unchanged on the basic safety file: move cars off low streets before high tide, do not drive through salt water, wash a car that did with fresh water, and treat flood water as a health hazard. That is also the insurance file. A parked car on Collins Avenue is comprehensive, not PIP and not NFIP. A ground-floor lobby or a storage cage is flood, not the HO-6.

An Application Dated Today Misses This Weekend

The shopping change is the wait, not a new federal form. The September 18 NFIP versus private guide still has the $250,000 / $100,000 Regular Program caps, no additional living expenses on the federal dwelling form, contents actual cash value, and Florida Statute 627.715 private-flood categories. What changed this morning is the calendar against an application dated October 23.

Public Law 119-103 still authorizes the National Flood Insurance Program through December 11, 2026. That cliff is a late-November article if Congress has not acted. It is not a reason to republish the shopping guide this morning. Jewelry and scheduled personal property on a Collins Avenue HO-6 remain a Coverage C sublimit conversation — typically $1,000 per item / $10,000 per loss on many Florida unit-owners worksheets unless scheduled — and still not this weekend’s flood file.

What ZIP 33160 Should Do Before Saturday’s High Tide

The useful work this morning is not renaming Josephine. It is matching the Coastal Flood Advisory to the policy that actually pays standing salt water, and matching the parked car to comprehensive.

• Confirm whether flood insurance is already in force on the house, the unit’s improvements and contents, or the association’s master policy. An HO-3, HO-6, or HO-4 still generally excludes external flood. A takeout that moved on October 20 did not buy that layer.
• If you drive in 33160 this weekend, treat Collins Avenue, low garage stalls, and flooded side streets as a comprehensive risk. Florida PIP still does not repair the car. Miami- Dade physical-damage inspection rules before adding comprehensive still apply if you are shopping that coverage after the fact.
• If a hotel bill is the worry, read additional living expenses against the peril. Wind ALE does not follow a king-tide flood. NFIP’s dwelling form still has no Coverage D. Private flood may.
• Citizens can still bind new and increased coverage this morning because Florida is not under a tropical watch. Binding wind on Friday does not create flood coverage for Saturday’s high tide.
• A November 5 choice deadline for the November 17 Citizens assumption is still on the personal-lines calendar if you have that packet. Do not file an Offer Form code because a flood advisory is in effect. That round stays on the October 20 calendar page.

Request a flood quote, a condo quote, or an auto quote if you want a 33160 worksheet against this weekend’s advisory, Tuesday’s peak, and the next king-tide window. A quote request does not bind coverage.
