Is El Niño coming to my state? What NOAA says for winter 2026-27

Last reviewed: Oct 24, 2026

Follow your local authorities. In an emergency call 999/911.

The short answer

It is not "coming": El Niño is already here. NOAA's Climate Prediction Center (CPC) has an El Niño Advisory in effect, and in its 8 October 2026 discussion says a strong-to-very-strong El Niño is likely through January-March 2027, "remaining greater than an 83% chance" (NOAA CPC, 8 Oct 2026). The useful question is what it changes for your state.

CPC also says that with an event this size, "the chances of experiencing impacts consistent with El Niño are larger, though not guaranteed". A tilt in the odds is not a forecast for your street.

What NOAA's winter outlook says, by region

These are CPC's own words for November-December-January from its seasonal outlook discussion of 15 October 2026 (NOAA CPC, 15 Oct 2026):

• Wetter than normal favoured: much of California, the Southwest, the Central and Southern Plains, the Lower Mississippi Valley, the Southeast and the eastern seaboard. The greatest likelihood is in the Southeast and Florida.
• Drier than normal favoured: the Northern Rockies and High Plains, parts of the Great Lakes, and interior Alaska.
• Warmer than normal favoured: the northern tier and western third of the contiguous US, south Florida, the Ohio Valley and the mid-Atlantic. Near-normal is favoured for much of the Southeast.
• Equal chances (no tilt either way) in areas shown white on CPC's maps. If your state sits there, the outlook does not say more or less is likely.

Find your own county on the CPC maps: CPC 90-day outlooks. We have not read tilt magnitudes off those maps, so we give none.

States with a full checklist

Four states have a costed, sourced checklist with a top-10 list, deadlines and a printable PDF:

• California
• Florida
• Texas
• Louisiana

Every other state is listed in the state and region finder, which says plainly that there is no costed table yet and points to official national tools; the generic kit list and documents grab-bag on the US index apply anywhere.

What it does not tell us

• It does not say when or where a storm will hit. Watches and warnings from the National Weather Service do that; see watch vs warning for what each means and what to do.
• It does not say whether you would be told to leave. Evacuation wording differs by county: see evacuation terms.
• Past strong El Niño winters were wet in the southern tier, but each one differed. Do not treat any past winter as a forecast.

What to do now

1. Open your state's checklist above, or find your state in the finder, and start with the top 10 actions.
2. If you own or rent in a flood-prone place, find out about flood insurance now. FEMA's FloodSmart says a new National Flood Insurance Program policy normally has a 30-day waiting period before cover starts, with a few listed exceptions (FloodSmart, buy a policy). A policy bought today normally starts about 30 days later, so do not wait for a storm forecast.
3. Save your local emergency alert sign-up and know your evacuation zone before the first storm, not during it.

The UK signal is weaker and less reliable than for the southern United States, and our confidence in any UK effect is low. See the UK plan for both outcomes or the UK index.
