Altoona, United States - January 11, 2026 A severe snow squall battered Interstate 99 south of Altoona at approximately 4:17 PM local time on January 11, 2026, creating dangerously low visibility for drivers. Footage captured from a moving vehicle shows heavy snow and gusty winds reducing sight distance to just a few dozen yards. Tire tracks and lane markings are barely visible as snow accumulates on the curving, multi-lane highway. The squall’s intensity blows snow horizontally across the windshield, forcing drivers to slow dramatically. In the distance, faint red taillights of vehicles ahead pierce the swirling storm. Roadside features, including metal guardrails, snow-covered embankments, and rocky hillsides, are partially obscured by the blizzard. Bare trees and a green highway sign appear through the thick snowfall, highlighting the challenging conditions. The event demonstrates the sudden and localized nature of snow squalls in central Pennsylvania, producing whiteout conditions and hazardous travel within minutes. Drivers are urged to exercise caution during similar winter storms, which can strike quickly and severely reduce visibility.
