Peak Season Is September 10: The Storm-Readiness and Post-Storm Restart Checklist for Florida and Puerto Rico Plants

If you run a plant in Florida or Puerto Rico, you've seen the headlines: NOAA's updated 2026 outlook calls a below-normal Atlantic season most likely — a 75% chance, against 20% near-normal and a nominal 5% above-normal, with 70%-probability ranges of 7–13 named storms, 2–6 hurricanes, and up to 2 major hurricanes. Before anyone relaxes, read what NOAA prints in the same outlook: "Hurricane-related disasters can occur during any season, even for years with low overall activity. It only takes one hurricane (or tropical storm) to cause a disaster. It is crucial that residents, businesses, and government agencies of coastal and near-coastal regions prepare for every hurricane season regardless of this, or any other, seasonal outlook."

That's not our editorializing — that's the forecast agency's own caveat, in its own outlook. A seasonal probability is not your site's risk. And NOAA is equally plain about the other thing a below-normal headline tempts people to infer: NOAA does not make seasonal landfall predictions at all, because landfalls are determined by the weather patterns in place as a storm approaches — usually predictable only days out. Nobody can tell you in September whether your county gets hit. What the climatology can tell you is when to be ready: the peak of the Atlantic season is September 10, most activity occurs between mid-August and mid-October, and the season officially runs through November 30.

What "peak season" means on a maintenance calendar

The National Hurricane Center's climatology gives peak season an operational shape. An average season (1991–2020 baseline) produces 14 named storms, 7 hurricanes, and 3 major hurricanes — and the benchmark dates cluster right now: the typical season has produced its 3rd hurricane by September 7, its 8th named storm by September 9, its 4th hurricane by September 16. NOAA's updated outlook adds that most of 2026's predicted activity "is likely to occur during August-September-October (ASO), the peak months of the hurricane season."

So the window you're in is roughly sixty days of elevated probability, and the useful framing is a deadline: everything on the pre-storm list below is work that has to be finished before a storm is on the map, because none of it can be done well in the 72 hours after a watch is issued. It's fitting that September 2026 is also National Preparedness Month — FEMA's Ready Campaign announced this year's theme, "Americans Stand Ready," on August 11.

Before the storm: the electrical-specific preparation most plants skip

Generic hurricane prep — water, fuel, shutters, contact trees — is well covered elsewhere. What's usually missing from a plant's plan is the electrical-specific work, and NFPA's guidance on using NFPA 70B for disaster recovery says the quiet part: planning for recovery "can, and should, happen well in advance of the hurricane ever showing up on radar screens."

Four items from that guidance belong on the plant list specifically:

De-energize, elevate, or remove. NFPA names "deenergizing equipment as well as elevating or removing critical equipment altogether" as electrical-specific pre-storm steps. Walk the facility now and decide, panel by panel and drive by drive, what gets powered down in an orderly shutdown, what can physically move above the plausible water line, and what leaves the building. Doing that triage during a hurricane watch is how critical spares end up underwater.

Contract qualified recovery help before you need it. NFPA's guidance notes that recovery contractors "can be contracted with ahead of time in order to ensure they are available when the need arises" — and that wherever a task requires a qualified person, that requirement holds whether the labor is in-house or outsourced. After a regional event, every qualified electrical contractor within 300 miles is booked. The plants that recover first are the ones holding pre-event agreements.

Write the site-specific safety plan now. Per the same guidance, "a site-specific safety plan should be in place before any potential disaster occurs" — lockout/tagout, test-before-touch, application of safety grounds, and PPE. If your restart plan exists only in the maintenance manager's head, it doesn't exist.

Document the system as it stands. The post-storm evaluation described below turns on knowing what was installed, where, and in what condition. Panel schedules, one-lines, and equipment inventories are cheap to update in fair weather and irreplaceable after.

Planning ahead is the whole game here — the same logic that's moving maintenance from reactive firefighting to a budgeted program applies double when the triggering event is a storm.

After the storm: the re-energization decision

Here's where plant staff actually get stuck — standing in front of a panel that took water, with production asking when the line restarts. The answer is already written down, and it's more conservative than most people expect.

NEMA publishes the definitive classification in Evaluating Water-Damaged Electrical Equipment (current edition © 2019), addressing exactly this scenario — equipment exposed to water through flooding, fire-fighting activities, hurricanes, and other large-water events — and it opens with the governing warning: "Electrical equipment exposed to water can be extremely hazardous if reenergized without performing a proper evaluation and taking necessary actions," with evaluation to be conducted by qualified personnel. For coastal Florida and Puerto Rico sites, one sentence deserves particular attention: "Ocean water and salt spray can be particularly damaging due to the corrosive and conductive nature of the saltwater residue." Storm surge is not rainwater.

NEMA's determination sorts equipment into a replace column and a may-be-reconditioned column, device type by device type. We're deliberately not reprinting those tables here — they're NEMA's reference material, and the current edition on nema.org is the copy your team should be reading. What a maintenance manager needs to carry into the walkdown is the pattern:

Anything electronic or semiconductor-based tends toward replacement. Drives, solid-state controls, electronic trip units and protective relays — the sealed, small, and electronics-dense end of the panel. The line that surprises people most: dry-type transformers, regardless of kVA rating, sit in the replace column too.

The reconditioning candidates are the large, mostly electromechanical equipment — the switchboard-and-motor end of the room, where reconditioning by properly trained personnel after consultation with the manufacturer is even possible, with the potential varying by the equipment's function, age, degree of flooding, and time under water.

And "may be reconditioned" is a conditional, not a green light. NEMA's own table intro makes it the condition: where equipment "may be reconditioned," it is "critical that the manufacturer of the equipment be contacted for specific guidance" — because attempts to recondition without consulting the manufacturer "can result in additional hazards" from improper cleaning agents or improper reconditioning techniques. The guidance also states plainly that it is not intended to override the specific equipment manufacturer's recommendations, and — worth knowing when you're sourcing replacements after a regional event — that distributors "should not supply any inventory that has been subjected to water damage."

To be explicit about what this article is and isn't: we're describing NEMA's published determination so you know such a determination exists and where it lives. Nothing here tells you that any specific piece of your equipment can be re-energized. That decision belongs to qualified personnel evaluating your actual equipment, with the manufacturer's guidance, every time.

One adjacent trap: an enclosure's ingress rating describes tested protection against specified water exposure — it is not immunity to flood immersion or salt-water contamination, and NEMA's replace-or-recondition determination governs regardless of what's printed on the nameplate. If your team is fuzzy on what those ratings actually promise, our IP67 vs. IP69K vs. NEMA 4X explainer draws the lines. (If the storm forces a panelboard or switchboard rebuild anyway, it may also be the moment to look at how cabinet wiring is changing before rebuilding to the old print.)

The sequence, not just the list

Knowing what to evaluate is half the problem; the other half is order of operations. NFPA 70B, the Standard for Electrical Equipment Maintenance, contains Annex K — a sequenced set of event phases to address before returning an electrical system to operation after a catastrophic event. NFPA notes the annex isn't part of the standard's specific requirements, but calls it "an invaluable resource to those recovering from a catastrophic event." The phases NFPA lists run from the initial event through securing the facility, mobilizing recovery personnel, developing the safety plan, temporary and emergency power generation and initial damage assessment, documentation, equipment work, re-energization, system commissioning, and a project summary. (Consult the standard itself for the full annex; NFPA's blog summary is the public description, and — as NFPA puts it — "it is well understood that water and electricity do not mix," so special attention goes to anything that took water before re-energization is attempted.)

For the human side of recovery work, OSHA publishes a Hurricane eMatrix outlining the activities most commonly performed during hurricane response and recovery, the hazards associated with each, and recommendations for PPE, safe work practices, and precautions per activity. Put the link in your recovery binder now.

What Florida and Puerto Rico have staged this season — and what it means for your plan

The public infrastructure picture this season is worth knowing, because it frames your own restoration expectations. Florida's emergency-management chief opened the season with "Preparedness starts long before a storm forms" (FDEM Executive Director Kevin Guthrie, at the June kickoff where the state announced CORE — the Coalition for Operational Readiness in Education — linking FDEM, the Department of Education, FloridaCommerce, higher-education institutions and private-sector partners). In Puerto Rico, the June 1 announcement from La Fortaleza reported PRASA operating 1,517 emergency generators (up 39 from last year), the emergency-management bureau running exercises across all 10 zones and 78 municipalities, and 344 shelters staged with capacity for 47,561 people. LUMA filed its 2026 Emergency Response Plan reporting more than $400 million in materials and inventory — over 23,000 utility poles, more than three million feet of cable, more than 5,000 distribution transformers — plus a fleet of 2,500+ vehicles and 1,300+ field employees, and a new process for post-event damage documentation.

Read that the right way: the utilities and agencies are staging for restoration, which is genuinely good news — and restoration timelines are still measured in days to weeks after a major event, which is why your plant's plan has to assume a gap. Extended generator operation after a storm is also exactly the kind of unbudgeted energy cost that compounds the trend line in your already-rising power bill.

The checklist, compressed

Before (finish by the peak, not during a watch): the de-energize/elevate/remove triage, pre-contracted qualified recovery help, a written site-specific safety plan with LOTO and grounding, current documentation. After: nobody re-energizes anything that took water until qualified personnel have evaluated it; NEMA's determination sorts the equipment classes; "may be reconditioned" means call the manufacturer, always; the sequence follows the phases NFPA lists in Annex K; salt water moves everything toward replacement. And through all of it, NOAA's sentence stays taped to the office wall: it only takes one.
