get_atlas14_rainfall_depth
ClaudeReturns the NOAA Atlas 14 precipitation frequency depth, in inches, for one latitude and longitude at the fixed 24-hour duration and 100-year average recurrence interval, with source series, volume and version. Source: NOAA Atlas 14 Precipitation Frequency Data Server. A frequency statistic, not a forecast, flood map, parcel risk or confidence bound; other durations, intensities and metric units are not supported.
get_daily_rainfall_estimate
ClaudeReturns the NOAA MRMS radar-gauge estimated rainfall total, in inches, for the grid cell containing one point in the contiguous United States on one past UTC day from 2015-01-01 through yesterday. Source: Iowa Environmental Mesonet reanalysis of NOAA MRMS. A cell estimate, not a gauge reading, forecast or frequency; zero can mean no rain or no coverage.
get_flood_study_stream_profile
ClaudeReturns, per cross-section of one stream in one county study, water-surface elevations at 10, 4, 2, 1 and 0.2 percent annual chance in feet, with the vertical datum as recorded, study and source record. Source: FEMA DFIRM cross-section tables retained from FEMA Map Service Center packages; sealed snapshot, no live read. Modeled recurrence values, not observations, flood depths or forecasts; a frequency not held is listed, not zero. Up to 50 cross-sections per page.
get_nws_active_alerts_at_point
ClaudeReturns National Weather Service alerts that are active at query time for one latitude,longitude point (1 to 3 per call). Source: NWS weather.gov active alert feed. Active alerts only; area-wide and other filters are not supported. Zero alerts means none matched in that response, not an absence of weather risk.
get_nws_point_forecast
ClaudeReturns National Weather Service forecast periods (seven days) for one latitude and longitude, in US or SI units. Source: NWS weather.gov API gridpoint forecast. Periods are forecasts for one NWS grid point, not observations or active alerts; generatedAt, updateTime and period start and end times are returned.
get_river_gauge_metadata
ClaudeReturns the identity and observed and forecast status availability of one NOAA National Water Prediction Service gauge, by its five-character NWSLI ID. Metadata and availability only, without measurement values, warnings or trends; no location or nearby-gauge search. Unavailable status is missingness, not zero; retrievedAt is fetch time.
list_county_flood_studies
ClaudeReturns the FEMA flood study held for one five-digit county FIPS code (status, effective or issue date, source document) and a page of up to 50 of its streams with cross-section counts and station ranges. Source: FEMA DFIRM study cross-section tables retained from FEMA Map Service Center packages; sealed snapshot, no live read. Not a regulatory determination; the FEMA Flood Map Service Center is authoritative. A county not held says nothing about FEMA coverage; current effectiveness is unknown.
list_flood_warning_polygons
ClaudeLists up to 50 National Weather Service storm-based flood warning polygons issued in a UTC window of at most 3 days, summarized by label, phenomenon, centroid and vertex count, optionally within a bounding box. Source: Iowa Environmental Mesonet distribution of NWS warnings. Polygon outlines and valid periods are not returned; the source reads at most 2,000 polygons. A warning is an issued product, not observed flooding.
list_usgs_stream_sites
ClaudeReturns up to 3 active USGS stream sites with instantaneous-value data inside a WGS84 bounding box of at most 0.2 degrees per side, with site number, station name and coordinates. Source: USGS NWIS Site Service. Site metadata only, without readings, current water conditions or flood stages; the returned sites are not a complete inventory of the box.
query_levee_inventory
ClaudeReturns up to 25 leveed-area records for a state or a bounding box of at most 0.5 degrees, or levee-crossing records for a bounding box, without geometry. Source: U.S. Army Corps of Engineers National Levee Database public feature service. Inventory only: presence is not a safety rating or protection level, and absence does not mean no levee exists. No snapshot date is returned.
search_flood_storm_reports
ClaudeReturns up to 40 flash-flood and flood Local Storm Report points for one USPS state in a window of at most 14 days, with type, place name, remark (cut at 200 characters) and publisher valid time. Source: National Weather Service Local Storm Reports via the Iowa Environmental Mesonet. Reports are preliminary and unverified; an empty window does not show that no flooding occurred; reports are not an event count or damage measure.
search_ipaws_alert_archive
ClaudeReturns up to 3 archived public, actual IPAWS Common Alerting Protocol messages sent in a UTC window of at most 31 days, with CAP identifier, message type, event codes, headline, sent, effective and expiry times as published, and whether the message has a polygon or references. Source: FEMA OpenFEMA IPAWS Archived Alerts. flood_only filters the publisher page to event codes beginning FF, FL, FA or CF, which is not a complete hazard classification. Archived messages are historical records, not current warnings; counts describe one publisher page, not an archive total.
