National Overview — Monday, October 27, 2025
Two main weather makers will shape today’s driving: a Pacific storm continues over the Northwest with rain, gusty winds, and hazardous mountain snow, while a slow-moving system keeps heavy rain over parts of the Gulf Coast and the Southeast. Organized severe thunderstorms are not expected after 8 a.m. EDT, though general thunderstorms may linger in Florida. A cold front will push showers into the northern and central Plains, and cooler air settles into the Northwest.
Hotspot 1: Pacific Northwest and Northern Rockies — Hazardous Mountain Snow and Gusty Winds
What to expect: Periods of lower-elevation rain, strong ridgetop winds, and heavy snow above roughly 3,500–4,500 ft. Several inches to over 6 inches are likely in higher terrain, including parts of the Cascades, Tetons/Big Horns, and the Northern Rockies. A Winter Storm Warning remains in effect for the Teton and Gros Ventre Mountains through 6 p.m. MDT. Anticipate pass-level impacts with reduced visibility, slick grades, and plow delays. Chains may be required.
- Primary areas: WA, OR, ID, MT, WY
- Key routes: I-90 (Lookout Pass ID–MT; Homestake Pass MT), I-84 (Blue Mountains OR/ID), I-80 (WY, especially Rawlins–Laramie), I-5 near Cascade foothills
- Additional mountain corridors: US-26/287 over Togwotee Pass; WY-22 Teton Pass
- Logistics notes: Expect variable traction above pass level, blowing snow at ridgetops, and intermittent chain controls. Plan for slower travel and spacing around plows.
Hotspot 2: Central Gulf Coast and Florida Panhandle — Heavy Rain, Localized Flooding
What to expect: Re-developing bands of heavy showers and thunderstorms with local 2–5 inch totals possible early, followed by periods of heavy rain through the day. Flooding of low spots and poor-drainage areas is the main concern. While organized severe storms are not expected today, a few stronger cells with gusty winds are possible.
- Primary areas: Southern AL and the FL Panhandle
- Key routes: I-10 (Pensacola–Tallahassee), I-65 (Mobile vicinity)
- Driving impacts: Hydroplaning in heavier cells, rapid visibility drops, and ponding in construction zones and ramps. Allow extra braking distance and reduce speed in standing water.
Hotspot 3: Southern Appalachians and Interior Southeast — Soaking Rain, Pockets of Flash Flooding
What to expect: The Gulf system shifts inland today, bringing locally heavy rain to hill and valley terrain. Watch for ponding on grades, slick curves, and low visibility in heavier bands.
- Primary areas: Northern GA and AL into eastern TN/NC/SC
- Key routes: I-75 (GA), I-85 (Atlanta–Greenville–Charlotte), I-26 (Tri-Cities–Asheville–Upstate SC), I-40 (Knoxville–Asheville)
- Driving impacts: Water over roadway at dips and low crossings, reduced traction on long descents, and slower travel through mountain gaps.
Additional Notes
- Florida Space Coast: Very heavy rain at times. Expect slowdowns on I-95 and portions of I-4 near Orlando in downpours.
- Northern/Central Plains: A cold front pushes in scattered showers. Plan for wet roads and occasional spray; cooler air follows in the Northwest.
Truckers’ Safety Tip of the Day
Before ascending any Western pass today, verify chain and closure controls and stage early if needed. In heavy rain, never enter water-covered lanes—turn around if depth is uncertain. Increase following distance, use steady throttle on climbs, lower gears on long downgrades, and give plows and emergency crews extra room. Stay alert to local NWS statements and DOT updates throughout your route.
