NWS’s polygons as issued, or the zones a zone-issued alert names; SPC’s watches by their counties. Checked . Data: NOAA/NWS, NOAA/SPC.
Interactive imagery loads separately. Missing radar does not remove warnings or imply clear weather.
Alert outlines: NOAA/NWS; cell points/observed segments: IEM/NEXRAD. A warning polygon is not a tornado footprint.
Total lightning, including in-cloud activity. Not ground-strike locations or a safe-to-go-outside signal.
Cached lightning observations have not loaded. An empty map is not zero lightning.
Source-rendered snow depth and snow water equivalent for the lower 48. History changes this snow picture only; warnings and radar keep their own clocks.
Stored snow depth · footprint valid 2026-10-16 18:00:00 UTC, picture retrieved 2026-10-17 03:08:05.170 UTC.
No NOHRSC picture displayed on the interactive map.

NOHRSC footprint times are metadata; pixel analysis time is not independently verified. Snow-depth pixels have previously differed from the footprint time. This is modeled/assimilated snow analysis, not a measurement at a place. Unshaded and no-data areas do not establish zero snow.
Collector checked not reported; feed generated not reported. Zero cells does not establish coverage or clear weather. Observations from different radars are not merged.

Flood Warning
This is retained evidence, not current protective-action guidance. Segment cancellation does not establish that every part of the warning ended.
The polygon is a warned area, not a tornado footprint. NWS detection tags are independent of radar algorithms and reports.
Flood Warning issued October 16 at 9:01AM CDT until October 18 at 3:18AM CDT by NWS Austin/San Antonio TX
...The Flood Warning is extended for the following rivers in Texas... Rio Grande At Foster Ranch affecting Val Verde County. * WHAT...Moderate flooding is forecast. * WHERE...Rio Grande at Foster Ranch. * WHEN...From this afternoon to late Saturday night. * IMPACTS...At 15.0 feet, (4.6 meters), moderate lowland flooding into the right flood plain floods campsites below Dryden to Amistad Reservoir. Turbulence is very dangerous for swimmers, tubers and canoeists. Livestock are trapped in low areas of the channel and banks and potentially can drown. * ADDITIONAL DETAILS... - At 8:15 AM CDT Friday the stage was 9.3 feet. - Bankfull stage is 14.0 feet. - Forecast...The river will rise above flood stage late this afternoon to 16.0 feet just after midnight tonight. It will then fall below flood stage tomorrow afternoon to 11.4 feet Sunday morning. It will rise to 12.7 feet early Sunday afternoon. It will then fall again and remain below flood stage. - Flood stage is 14.0 feet. - Flood History...This crest compares to a previous crest of 16.0 feet on 10/01/1991. - http://www.weather.gov/safety/flood
Motorists should not attempt to drive around barricades or drive cars through flooded areas. Be especially cautious at night when it is harder to recognize the dangers of flooding. Even 6 inches of fast-moving flood water can knock you off your feet and a depth of 2 feet will float your car. Never try to walk, swim, or drive through such swift water. If you come upon flood waters, stop, turn around and go another way. Please report observed flooding to local emergency services or law enforcement and request they pass this information to the National Weather Service when you can do so safely. Additional information is available at www.weather.gov. The next statement will be issued this evening at 915 PM CDT.

Not an official warning service. Warnings and watches are the National Weather Service’s, outlooks and reports the Storm Prediction Center’s and the Weather Prediction Center’s (Data: NOAA/NWS, NOAA/SPC, NOAA/WPC). When a warning is issued for you, act on it, and use weather.gov or a NOAA Weather Radio for where you are.
