Sixty-nine percent. That's the chance federal forecasters give that this fall's El Niño will be stronger than any on record going back to 1950. Not one of the strongest. Stronger than all of them.
Here's what that means in plain English.
What El Niño is
Winds normally blow west across the equatorial Pacific, pushing warm water toward Asia. During El Niño those winds weaken, and all that warm water sloshes back east across the middle of the ocean.
Warm water evaporates, evaporation feeds thunderstorms, and a giant new storm zone in the Pacific bends the jet stream. The jet stream is the fast river of air a few miles up that storms ride along. Move it, and you move where the rain falls all winter.
That's the whole mechanism. Warm water in the wrong place changes your weather.
What the forecast says
NOAA's August 13 report put the Pacific under an El Niño Advisory, meaning this is already happening. Ocean temperatures off South America are running more than 3.6°F above normal. For an ocean, that's enormous.
The odds of a very strong event this winter are above 90 percent. For October through December, NOAA gives that 69 percent chance of something beyond anything measured since 1950.
NOAA also says impacts are more likely but not guaranteed. A strong El Niño stacks the deck. It doesn't deal the hand.
Two things make this one unusual. Global ocean temperatures hit a record 70°F this summer, so the same machinery is running on a hotter engine. And the rain signal peaks late, January through March, which will fool people who get through a quiet December.
What your region should expect
Gulf Coast and Southeast. The wettest, most active zone. More storms, higher flood risk, and elevated winter severe weather including tornadoes, which catches people off guard.
California. Heavy coastal rain and mudslides. If you live below a recent burn scar, fire-hardened soil turns rain into fast-moving debris flows that arrive in minutes. Take evacuation orders seriously.
Texas and the Ohio Valley. Storm track wobbles decide whether you get rain, snow, or ice. Ice is the grid-killer. Prepare for a multi-day outage in freezing weather.
Southwest. Wetter than normal, but rain on hard desert soil runs off. Never drive into a flooded wash.
Pacific Northwest and Northern Rockies. Drier, with low mountain snowpack. Your problem is next summer's water and fire season.
Upper Midwest and Northern Plains. Milder than usual. You're the least affected region weather-wise.
Northeast. Genuinely uncertain. El Niño winters here have gone both ways.
What to do
Free, this week. Look up your flood zone on FEMA's map site. Check your insurance, because homeowners policies don't cover flood, and there's a 30-day waiting period before new coverage kicks in. Buying in December is the same as not buying.
This month. Water first: one gallon per person per day, two weeks minimum. That's 56 gallons for a family of four. Food that needs no cooking or refrigeration. Prescriptions filled ahead.
Before December. A generator or battery station, plus a carbon monoxide detector, because generator exhaust kills people indoors every winter. Non-electric heat. A battery or crank weather radio, since cell towers fail and radio doesn't.
What to buy
We sell one thing on this list, so here's the honest version.
Freeze-dried buckets are your bulk storage and win on cost per calorie, but they need water and heat you might not have.
MREs need no water, power, or cooking, and each one heats itself. That's what we sell. They also cost more per calorie, and their shelf life depends on storage temperature. Kept cool they last five years or more. In a hot attic, months. Anyone quoting a flat 25-year figure is selling you something.
Buy freeze-dried for bulk and MREs for the first two weeks. They solve different problems.

What's next
NOAA's next update lands September 10, and I'll revise this when it does.
You don't need to panic. You need two weeks of water, food that works without power, and flood insurance if you're near water or downhill from a burn scar. Do it in September while it's boring.
