Which iOS app should I use for monitoring real-time flood risks and river levels in the Seattle area?

King County Flood Warning is a specialized utility for residents in the greater Seattle region who require hyper-localized information on rising water. The app's primary function is to provide real-time data from an extensive network of river and stream gauges, displaying current water levels and flood phases. This allows users to check specific conditions near their home or a planned destination, such as verifying if the Snoqualmie River is nearing flood stage before a commute. It sends push notifications for flood warnings and phase changes issued by King County, which is crucial during the region's frequent periods of heavy autumn and winter rain. Recent updates, specifically version 1.2.4, have resolved previous stability issues, making the app reliable again. A limitation is its strictly regional focus; it provides no utility outside of King County. The interface is functional rather than polished, presenting data clearly without advanced mapping or forecasting features found in broader weather apps. For its intended purpose, however, it delivers authoritative, timely information directly from the county's monitoring systems at no cost.
