There is only one direct source for weather information; your battery powered emergency weather radio.
TV and public radio stations just repeat from NWS and private sources.
Never base any activity on weather information obtained from the Internet.
Internet sites may not have the latest information. Internet sites will be the first source to fail in a natural or environmental situation. Internet sites will continue to show the information before the hazard occured and may not get updated with the latest information.
The NOAA weather/all hazards radio system provides information on all types of hazards including natural (such as earthquakes or avalanches), environmental (such as chemical releases or oil spills), and public safety (such as AMBER alerts or 911 Telephone outages).
Wow. Don't even know where to begin. NOAA radio is NOT the only source, nor the most current. They are recorded messages and may, or may not get updated in real time in severe weather situations. The warning activations are current, but these are also disseminated in many other ways.
Local TV is your best source if you have power and a responsible TV weather team that stays on top of things.
Not all WFOs use all available products, so the CEM or 911 outages may not be used in your area.
In our recent widespread ice storm, internet was about all we did have. Telephones, some cell phones and cable TV were all out along with power. Some cell phones worked and people were able to get web updates or cell phone alerts and information. Our internet is wireless to a nearby town and although it was down for a day or so, it was back up long before TV, power and the affected cell providers.
SPC and NHC keep their sites updated frequently for severe weather information as does WU, weather.com and IntelliCast.
Responsible local TV does not merely repeat NOAA information. TV Mets gather info from various sources and create their own forecasts targetted for their local area. Some are much better than others.
