NOAA/NWS/NOHRSC’s original picture and legend. No station or address value is inferred.
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.
A Red Flag Warning means that critical fire weather conditions
are either occurring now, or will shortly. A combination of
strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.
The polygon is a warned area, not a tornado footprint. NWS detection tags are independent of radar algorithms and reports.

Red Flag Warning issued October 16 at 5:51PM CDT until October 17 at 7:00AM CDT by NWS Brownsville TX
...STRONG NORTHERLY WINDS TODAY AND TONIGHT WILL INCREASE
WILDFIRE THREAT...
.A strong cold front will push south through Deep South Texas and
the Rio Grande Valley today, with a secondary surge of strong
northerly winds arriving late this evening through late Saturday
morning. Relative humidity values are expected to drop this
afternoon with little to no recovery into Saturday morning. Any
wildfire that can develop will behave dangerously with erratic
growth and spread due to strong winds and lower humidity. A Red
Flag Warning remains in effect.
* WINDS...North 15 to 25 mph with gusts up to 45 mph.
* RELATIVE HUMIDITY...As low as 24 percent.
* IMPACTS...Any fire that can develop will behave dangerously
with erratic growth and spread.
A Red Flag Warning means that critical fire weather conditions
are either occurring now, or will shortly. A combination of
strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.

Snow on the ground
NOHRSC snow depth and snow water equivalent use the source’s original pictures and legends, with qualified footprint times. Open the cached source page for availability and retained history. This wall has no snow picture to rotate; missing imagery does not mean no snow.
Drawn by the Analysis tab’s own renderer. Data: NOAA/SPC, NOAA/NCEP.
The tropics
NHC’s and JTWC’s storms, their official graphics and the watches and warnings for them. Storm Mode’s own tropical panels arrive with its tropical events.
