National Overview — Wednesday, October 1, 2025

No organized severe thunderstorms are expected today. Unsettled weather persists in the West with rounds of rain and cooler highs, while late-season warmth continues across much of the Plains and Midwest. Offshore hurricanes are generating dangerous surf and rip currents along parts of the East Coast, bringing gusty coastal winds and hazardous marine conditions.

Pacific Northwest (WA/OR) and Adjacent High Terrain

Repeated rain bands will focus on western Washington and northwest Oregon, with the heaviest totals over the Olympic Peninsula. Roads will be wet much of the day, with localized runoff issues and ponding in poor drainage areas. Late today into tonight, light high-elevation snow is possible at the higher passes in the Cascades and into the northern Rockies, creating slick spots.

Impacts: Wet roads, reduced traction, localized runoff/ponding; late-day slick spots over higher passes due to light snow.
Winds/Coast: Coastal spray and gusty winds may affect visibility and vehicle control along exposed coastal stretches.
Primary corridors:
- I-5: Periods of heavy rain with wet roads and ponding.
- US-101: Coastal spray and wind.
- I-84 (Columbia River Gorge): Periods of rain; watch for spray and changing visibility in the Gorge.
- I-90: Watch higher passes for slick spots tonight into Thursday.
Driver notes: Slow down on oil-slicked wet pavement, extend following distance, and check pass conditions before climbing into the Cascades late day and overnight.

East Coast of Florida (Daytona Beach to Miami)

Persistent onshore flow continues to drive repeated heavy showers ashore, with localized flash-flooding potential and gusty easterly winds. Expect brief water over roadways, areas of poor drainage flooding, and quick drops in visibility under heavier cells.

Impacts: Hydroplaning risk in heavy showers; standing water in low spots; reduced visibility in downpours.
Winds: Gusty easterlies may push high-profile vehicles near the immediate coast.
Primary corridors: I-95 and Florida’s Turnpike.
Driver notes: Avoid flooded lanes, keep speeds down in heavy rain, and allow for longer braking distances.

Mid-Atlantic and New England Coasts

Long-period swells and high surf from offshore Hurricanes Humberto and Imelda are producing hazardous marine conditions and gusty coastal winds. Beachfront routes and bridges may experience crosswinds and blowing spray. Portions of NC Highway 12 on the Outer Banks have seen closures from overwash and debris—plan detours and check status before heading out.

Impacts: Crosswinds on exposed bridges and causeways; spray reducing visibility; isolated overwash/debris issues in vulnerable coastal spots.
Primary corridors: Coastal stretches of I-95 from North Carolina to New England; NC Highway 12 on the Outer Banks.
Driver notes: Use caution on bridges, reduce speed in gusts, and verify coastal road openings—do not attempt to drive through overwash.

Operations Snapshot

Many interior routes across the Plains and Midwest will be warm and generally quiet from a severe-thunderstorm standpoint today. Focus extra time and caution on the Pacific Northwest rain zones and along the Atlantic seaboard where coastal winds, surf, and showers are the main operational challenges.

Safety Tip of the Day

In heavy rain and coastal wind, slow down and keep both hands on the wheel. Increase following distance, avoid cruise control on wet pavement, and never drive through water covering the roadway. Before climbing mountain passes late today and tonight, confirm conditions and be prepared for slick spots at higher elevations.
