Forecast Zones are Not Enough
There is no limit to the number of warnings that a forecast zone can be under. In case of a wind chill advisory, a high wind warning, and an active blizzard warning, all at the same time, in the same place, in the same area.
Tornado Watches and Warning
A tornado watch means there is a good chance that a tornado will form in the area, whereas a tornado warning means a tornado is imminent or about to occur.
The World Weather Observatory Information System
It is worth remembering that no nation, rich or poor, can serve its citizens with the kind of timely and reliable weather information they have come to expect and depend on without the collaboration of all others. The World Weather Watch needs to evolve and grow. The World Weather Watch has evolved to take advantage of technological advancement in observing systems, for example in remote sensing, communications systems, and faster and more powerful super computing systems for data analysis and the running of dynamic weather, climate and environmental prediction models.
The technical systems of the programme need advanced technology in order to be improved. The WMO policy on free and unrestricted international exchange of meteorological and related data and products is ensured by the WMO Information System. Every day, the data and derived products are freely exchanged between WMO centres and weather offices in each country thanks to WMO.
The term "watch" in the NWS
The term watch is used by the NWS when a weather condition is likely to occur over an area. A watch is not certain of its location and timing. The main purpose of a watch is to give people enough time to make changes to their plans so that they can be seen.
The GDPFS: a system of observation systems for the WMO
The system of observing systems is based on the requirements of the WMO programmes. It ensures the availability of required data and information and facilitates access through the WMO Information System according to identified temporal, geographical and organizational requirements. It helps ensure high data-quality standards and benefits by respecting data-sharing policies.
The structure of the organization will improve the availability of observational data and products. It will provide a single focus for managing all WMO observing systems and a mechanism for interactions with co-sponsored observing systems. Integration will lead to savings and efficiency that can be reinvested to overcome known deficiencies and gaps in the present structure.
The quality of service is guaranteed when the network is under the control of NMHSs, as is the asset of the closed network such as the GTS. The problem is that it is limited by the cost of connecting between centres. The Internet can handle large volumes and, since the early 1990s, driven by the growing data volumes associated with improving numerical weather prediction models and rapidly increasing data volumes associated with remote-sensing from new improved satellite systems, some NMHSs established bilateral links for exchanging data.
There are many other GDPFS initiatives, including the use of ensemble-based science in operational use, improved fine-scale modelling at national centres, expanded use of ever-improving NWP products in many meteorological applications, and improved international collaboration long-range forecasting. The GDPFS has seen continuous improvements in scientific and technological developments, the establishment of standards for product exchange and the provision of training and capacity-building measures for NMHSs of developing countries. The second theme states that user needs may influence not only the end product but also feedback all the way to the choice of observations taken, models and other processing tools used, depending on how specific high-impact weather, climate and water events may affect user groups.
A Warning for the Presence of a Potentially Hazardous Space Weather Event
A Watch issued when the risk of a potentially hazardous space weather event has increased significantly, but its occurrence or timing is still uncertain. It is intended to give enough notice so that those who need to set their plans in motion can do so. A watch is a notification of possible space weather activity with a lead-time of hours to days.
A higher-level watch can be upgraded. A warning issued when a significant space weather event is imminent or likely. A warning is a high confidence prediction of imminent activity.
Severe Thunderstorm Watching
A Severe Thunderstorm Watch does not mean that severe weather has been reported, but it does mean that conditions are just right for the development of severe weather. While no immediate action is required for the issuance of a watch, citizens should be prepared to seek shelter if necessary and keep up to date on the current weather situation. A tornado warning is a very specific severe thunderstorm warning and means that a tornado has been spotted by a human observer or indicated by a doppler radar.
A Winter Storm Watch
A Winter Storm Watch issued when there is a chance of a winter storm within 48 hours. It does not mean that winter weather will be bad. When wind chills of -5 to -19F are expected east of the Blue Ridge Mountains, and when wind chills of -10 to -24F are expected along and west of the Blue Ridge Mountains, a Wind Chill Advisory issued.
When wind chills of -20F or lower are expected east of the Blue Ridge Mountains, and when wind chills of -25F or lower are expected along and west of the Blue Ridge Mountains, a Wind Chill Warning issued. A Severe thunderstorm watch issued when there is a chance of severe storms. It doesn't mean that they will happen.
It only means they are possible. A tornado watch issued when there is a chance of tornadoes. It doesn't mean that they will happen.
On the scalar field theory of quantum mechanical systems
Both can be fine. The answer can be either one of the two ways, depending on how the listener chooses to interpret the question.
Red Flag Conditions
Informs land management agencies of the Red Flag conditions. When there is high confidence that Red Flag criteria will be met within the next 24 to 48 hours, or when those criteriare already being met or exceeded, a Red Flag Warning will be issued. A warning may be issued for all of the area. The Red Flag Warning product will include zones impacted by the event.
Severe Weather Watching
A tornado warning means you need to take shelter. A tornado is possible. A tornado warning is usually for a short period.
There is a chance for a severe thunderstorm to move in. The time period is similar to a tornado watch and lasts about 6 hours. Severe weather watches are not the same as winter weather watches.
A Map for the Warning Spot of Severe Storms
For the past decade, warnings for severe storms are no longer issued on a county level, but a map issued to show the warning spot. If a tornado or flash flood warning issued, your cell phone might go off if you are inside the polygon.
Red Flags and Fire Weather Watched
The public and area management officials are warned of the potential threat to life and property if a fire starts, if a red flag is likely to be met. A Fire Weather Watch issued 24 to 48 hours before red flag criteria is expected to occur, whereas a Red Flag Warning issued when red flag criteriare already occurring or will occur within the next 24 hours or less.
