Current SE Utah Slot Canyon Conditions

See recent Utah slot canyon conditions based on radar rainfall, watershed runoff modeling, and canyon-specific pool-storage estimates. This tool tracks 22 technical canyons and identifies storms likely to produce partial refill, major refill, or flushing. Additional canyons will be added in future versions.

Conditions are modeled from weather radar and watershed characteristics rather than direct field observations. Results can help canyoneers identify which drainages received meaningful rain, but they do not represent current flash-flood clearance or guaranteed pool depths.

Additional Flash-Flood Planning Tool

After reviewing the current canyon conditions, use our Flash Flood Risk Assessment Tool for another layer of trip planning. The interactive mapper evaluates canyon-specific characteristics, watershed size, historical climate patterns, and precipitation intensity to help identify which canyons may be more vulnerable to flash flooding.

This tool is intended to supplement—not replace—current weather forecasts, radar, National Weather Service alerts, and sound judgment. Always check the latest forecast before entering a canyon, including weather occurring upstream within the entire drainage basin.
