Offline Weather Forecasts for the
Colorado Trail.

The CT is famous for extreme altitude and dangerous afternoon monsoons. Avoid getting stranded above treeline by pulling hyper-local weather alerts directly to your phone via satellite SMS, no cell service required.

Navigating the
Summer Monsoon Sequence

The Colorado Trail boasts an incredibly high average elevation, threading through remote ranges like the San Juans and Collegiate Peaks. During peak hiking season in July and August, hikers are constantly managing the North American Monsoon—intense, rapidly forming thunderstorms that materialize out of nowhere in the early afternoon.

With hours of exposed, above-treeline hiking required daily, guessing when a dark cloud will turn into a significant storm based on a days-old town forecast makes it hard to plan your daily mileage confidently.

A Smaller, Smarter Way
To Carry Safety Out Into The Rockies

In previous years, navigating the alpine safely meant packing a heavy, expensive satellite device like a Garmin InReach just to pull off-grid weather through a pricey subscription plan. Today, if you're carrying a modern smartphone (like an iPhone 14+ running iOS 18, or a Google Pixel 9 / Samsung Galaxy S25 series phone running Android 15+), you can use its native satellite texting capabilities to interface directly with SMS Weather On Demand.

Crucial Benefits for the CT

Coordinate Grid Accuracy A regional forecast for "Leadville" is irrelevant when you are climbing Hope Pass. Text your exact GPS coordinates via satellite, and we'll pull the localized forecast specifically matched to your exact geographic coordinates.
Real-Time Decisions Above Treeline Are those clouds just building or are they bringing 60mph gusts and hail? Pull a forecast right from your tent in the morning to make an informed, safe decision before stepping onto the ridge.
Pay-As-You-Go Economics Whether you are doing a 5-day segment hike or an entire thru-hike, skip the $35/month flat fee for emergency data. With our system, you only pay pennies for the exact forecasts you use out there on the dirt.

Safety First By removing the expensive recurring subscription barriers to off-grid weather, hikers can prioritize their safety in dangerous alpine environments.
