Frequently Asked Questions
How does StormCast monitor river levels?
StormCast connects to USGS Water Services, which maintains thousands of real-time stream gauge stations across the US. You search for your local gauge, add it, and StormCast checks the level every 5 minutes.
Can I set my own alert threshold?
Custom thresholds are coming soon. Right now, StormCast alerts you automatically when a gauge crosses into a new NWS flood category — action, minor, moderate, or major.
How many gauges can I monitor?
Unlimited. Monitor your creek, the nearest large river, and a gauge upstream that gives you early warning — all at the same time.
What if my local gauge doesn't have an NWS flood stage defined?
That's common for smaller streams and tidal gauges. You can still track them to monitor water levels — flood category alerts work for gauges that have NWS-defined stages, and custom thresholds for all gauges are coming soon.
Does it work anywhere in the US?
Yes. USGS maintains gauges in all 50 states. If there's a gauge within reach of your area, you can monitor it in StormCast.
