POCATELLO, Idaho — A Winter Storm Warning is in effect across portions of Idaho and Wyoming through Friday, April 3, 2026, at 6:00 PM MDT, according to an alert issued by the National Weather Service (NWS) office in Riverton, Wyoming. The warning was activated on Wednesday, April 1, 2026, at 11:14 AM MDT, giving residents across Southeast Idaho and neighboring regions roughly two days to prepare for dangerous winter travel conditions heading into the Good Friday holiday weekend.
The warning covers a multi-day weather system bringing a combination of heavy snow, gusty winds, and freezing temperatures to the region. Residents of Bannock County, including those in Pocatello, Chubbuck, Inkom, and Lava Hot Springs, are advised to monitor road conditions closely and limit non-essential travel as the storm progresses through the area.
Storm Conditions and Travel Impacts
Forecasters are tracking a system capable of producing significant snowfall accumulations alongside strong wind gusts, which could create blowing and drifting snow. Such conditions typically result in reduced visibility and hazardous driving on major corridors through Southeast Idaho, including Interstate 15 and Interstate 86, both of which serve as critical travel and commercial freight routes through Bannock County.
The storm arrives ahead of the Easter weekend, a period when many Idaho families travel for holiday gatherings. Idaho State Police and local emergency management officials consistently urge drivers to check road conditions before departing, carry emergency kits in their vehicles, and allow extra stopping distance on snow-packed or icy surfaces.
The Idaho Transportation Department (ITD) maintains real-time road condition updates at 511.idaho.gov, and motorists are encouraged to check conditions along their entire planned route before heading out. Mountain passes and elevated highways in and around Bannock County are particularly vulnerable to rapid deterioration during late-season storms.
Late-Season Winter Storms Not Uncommon in Southeast Idaho
While April snowstorms may catch some residents off guard, late-season winter weather events are a recurring reality across Southeast Idaho. The region’s elevation and geographic position make it susceptible to significant snowfall well into spring, and the National Weather Service has issued similar late-season warnings in previous years during April and even early May.
Residents near the Portneuf River corridor and in communities at higher elevations — such as Inkom and areas along the I-15 corridor south of Pocatello — may see heavier accumulations depending on storm track and temperatures. Localized impacts can vary significantly across Bannock County based on elevation changes throughout the area.
The Pocatello Regional Airport may also experience operational impacts during periods of heavy snowfall or reduced visibility. Travelers with scheduled flights are advised to contact their airline and check for delays or cancellations as the storm moves through the region.
Idaho State University in Pocatello, along with local schools within the Pocatello/Chubbuck School District, could also face decisions regarding operations if conditions deteriorate significantly. Families should monitor official district communications for any schedule changes related to storm impacts.

What Comes Next
The Winter Storm Warning remains in effect until 6:00 PM MDT on Friday, April 3, 2026. Residents should continue monitoring the National Weather Service and local forecasts for updates as the storm system evolves. Road conditions will be updated in real time by the Idaho Transportation Department. Emergency management officials recommend that all Bannock County residents have an emergency supply kit available and stay informed through official channels throughout the duration of the storm.
