High Wind Watch, High Wind Warning, Wind Advisory: National Alert Roundup — Wednesday, March 11, 2026
A sprawling severe weather system stretching from the Pacific Northwest to the Ohio Valley has triggered a patchwork of high wind watch, high wind warning, and wind advisory alerts across more than a dozen states today. The National Weather Service is urging millions of Americans to prepare for damaging gusts, downed power lines, and dangerous travel conditions through Thursday.
High Wind Warning in Effect: Washington State and the Pacific Northwest
The National Weather Service office in Spokane issued a high wind warning for portions of North Central and Eastern Washington, including the Wenatchee and Okanogan Valleys, the Kittitas Valley, and the Simcoe Highlands. Southwest winds of 20 to 40 mph with gusts reaching 60 to 65 mph are expected from 8:00 PM ET Wednesday through 11:00 AM ET Thursday.
Communities under the high wind warning include Wenatchee, Leavenworth, Cashmere, Okanogan, Omak, Quincy, Moses Lake, Othello, Ritzville, and Grand Coulee, among others. Forecasters warn winds could be strong enough to blow down trees and power lines and cause widespread damage and safety concerns.
Wind gusts of 50 to 65 mph are possible across Eastern Washington, and areas of blowing dust along Interstate 90 through the Moses Lake area and central Columbia Basin could reduce visibility to less than a quarter mile, most impactfully Wednesday night through Thursday morning.
High Wind Warning: Central and North Central Montana
A significant wind event will impact Central and North Central Montana from late Wednesday evening through Thursday evening, with sustained winds of 35 to 55 mph lasting 12 to 18 hours and higher gusts expected throughout. A separate system will bring sustained winds of 35 to 45 mph to Southwest Montana for the same duration on Thursday.
The National Weather Service in Great Falls warned that the duration and magnitude of the winds will lead to dangerous driving conditions, power outages, property damage, and reduced visibility due to blowing dust. Officials strongly recommend delaying travel if possible on Thursday, especially for high-profile vehicles, and urge residents outdoors to watch for falling trees, limbs, and downed power lines.
Wind Advisory: Ohio and Indiana Tri-State Region
A wind advisory is in effect from 8:00 AM to 7:00 PM ET Wednesday for the entire Cincinnati Tri-State region covering parts of Ohio, Indiana, and Kentucky. Wind gusts up to 50 mph are possible throughout the day, running concurrently with an active tornado watch in effect through 6:00 PM ET for the same area.
In the Evansville, Indiana region, a wind advisory was in effect from 7:00 AM to 4:00 PM ET with wind gusts of 30 to 40 mph expected. An Alert Day is in effect through Wednesday evening, with multiple rounds of storms expected and all severe hazards on the table — damaging winds, large hail, and isolated tornadoes.
High Wind Watch vs. High Wind Warning vs. Wind Advisory: What Each Means
Understanding the difference between these three alerts can be life-saving. Here is what each designation means from the National Weather Service:
| Alert Level | What It Means | Wind Threshold |
|---|---|---|
| Wind Advisory | Nuisance winds causing minor hazards | Gusts 40–57 mph |
| High Wind Watch | Conditions favorable for dangerous winds soon | Gusts 58+ mph possible |
| High Wind Warning | Dangerous winds occurring or imminent | Gusts 58+ mph confirmed |
A high wind warning is the most serious of the three levels. When a high wind warning is issued, residents should secure outdoor objects immediately, avoid unnecessary travel — especially in high-profile vehicles — and stay away from trees and power lines.
Severe Weather Threat Continues Eastward Through Thursday
Isolated to scattered severe thunderstorms are expected Wednesday from the Arkansas-Louisiana-Texas region and Lower Mississippi Valley northeastward through the Ohio Valley and Mid-Atlantic, with heavy to excessive rain posing a flooding threat from east Texas into Upstate New York.
New storm development is expected Wednesday afternoon between 2:00 PM and 7:00 PM ET across the Ohio Valley, when a cold front approaches and shifts the primary risk toward damaging winds and tornadoes. The next severe weather threat after today is expected to arrive Sunday afternoon. Residents across all warned areas are urged to monitor the National Weather Service and local broadcast alerts for real-time updates throughout the day.
