2179: NWS Warnings
Title text: Kind of rude of them to simultaneously issue an EVACUATION - IMMEDIATE alert, a SHELTER IN PLACE alert, and a 911 TELEPHONE OUTAGE alert.
This comic portrays the NWS as a person that needs breaks, which is absurd, as it is an important service and would probably always have staff active, even on holidays. For example, the NWS continued to work during federal government shutdowns, as it was considered an essential service for the protection of life and property. Even if one of the NWS's 122 local weather offices were to be incapacitated, contingency plans are in place to ensure that nearby offices act as emergency cover; as happened in March 2019 with flooding in Nebraska forcing the NWS office in Valley to evacuate.
Regardless, in this comic the NWS has decided to take a break, and so has opted to issue every extreme weather alert possible for the entire contiguous portion of the United States (including DC, but not Alaska or Hawaii) to make sure no one is caught by surprise by extreme weather, since the NWS will not be able to issue warnings. As the NWS could not be sure which areas will need to get warned of severe incidents, the NWS has decided to issue warning polygons that cover the entire United States (ostensibly except Alaska and Hawaii). A layer of humor is that this would necessitate warnings where they would be highly unlikely to occur in real life; examples include issuing blizzard warnings for Florida, where any amount of snow is rare, and tsunami warnings for areas very far from any ocean coastline.
Each of the text warnings within the map are coloured, which matches the NWS color coding used for a given warning event.
The title text mentions how some of the warnings that have been issued require action to get to safety that contradicts the other warnings, for example, an evacuation warning and a shelter in place order, since doing one would mean failing to do the other. This confusing scenario would likely prompt many concerned citizens to call emergency services for clarification, but the 911 outage alert would advise against this, adding another layer to the absurdity of the occurrence of the NWS taking a break.
This comic was likely inspired by the heat wave that impacted two-thirds of the US for more than a week.
NWS and tornado warnings was later mentioned in the title text of 2219: Earthquake Early Warnings.
Table of warnings
Assumptions about text outside of the frame are given in square brackets. This page from the NWS lists all the warnings and colors, including all the hex codes for them which we
|Gale warning||Plum||In the United States, the National Weather Service issues gale warnings for marine areas (oceans, sounds, estuaries, and the Great Lakes) experiencing, or about to experience, winds within the range of 34 knots (63 km/h; 39 mph) to 47 knots (87 km/h; 54 mph). Listed twice.|
|Tornado Warning||Red||A tornado warning is issued for an area if a tornado is radar indicated, radar confirmed, or members of the public confirm the existence of a funnel cloud or a tornado. As tornadoes are more apt to form in different parts of the country at different times a country-wide tornado warning would be highly unlikely.|
|Flash Flood warning||Dark red||Flash flooding is occurring, imminent, or highly likely. A flash flood is a flood that occurs within six hours of excessive rainfall and that poses a threat to life and/or property. Ice jams and dam failures can also cause flash floods.|
|Air Quality [Alert]||Gray||An air quality alert informs the public about pollution levels in the air and advises vulnerable groups such as children and people with lung disease to take precautions.|
|Frost Advisory||Cornflower blue||Minimum sheltered temperatures are forecast to be 33 to 36 °F (1 to 2 °C) during the locally defined growing season on nights with good radiational cooling conditions (e.g., light winds and clear skies). Widespread frost can be expected. Listed twice.|
|Severe Thunderstorm Warning||Orange||A severe thunderstorm is indicated by Doppler weather radar or sighted by Skywarn spotters or other persons, such as local law enforcement. A severe thunderstorm contains large damaging hail of 1 inch (2.5 cm) in diameter or larger, and/or damaging winds of 58 mph (93 km/h) or greater. These warnings are currently issued on a polygonal basis.|
|Dense Fog Advisory||Slate gray||Widespread or localized fog reducing visibilities to 1⁄4 mi (0.4 km) or less.|
|[Hurricane Force W]ind Watch||Western red||A hurricane force wind watch is issued by the National Weather Service of the United States when the risk of sustained winds or frequent gusts of 64 knots (118 km/h, 74 mph) or greater are predicted to occur. The winds must not be directly associated with a tropical cyclone, or a hurricane warning will be issued.|
|Tropical Storm Warning||Firebrick||A warning that sustained winds within the range of 34 to 63 kn (39 to 73 mph or 63 to 117 km/h) associated with a tropical cyclone are expected in a specified area within 36 hours or less.|
|Ice Stor[m Warning]||Dark Magenta||Heavy ice accumulations are imminent. The criteria for amounts vary over different county warning areas. Accumulations range from 1⁄4 to 1⁄2 inch (6.4 to 12.7 mm) or more of freezing rain. Listed twice.|
|[Extreme Cold] Warning||Blue||The NWS does not issue cold warnings. As the text is cut off, Randall probably means Extreme Cold Warning, which the NWS offices in Alaska issue. This implies that the entire U.S. will get colder. This does not make sense, partly because in the time this comic was released, it was summer in the U.S., but also because Alaska, the one state that does receive this type of warning, is not shown.|
|Heat A[dvisory]||Coral||High Heat Index (HI) values are forecast to meet or exceed locally defined warning criteria for one or two days. Typical HI values are maximum daytime temperatures above 100 to 105 °F (38 to 41 °C) and minimum nighttime temperatures above 75 °F (24 °C).|
|[Flood] Advisory||Spring green||For nuisance type flooding meeting one of the following criteria: <3 feet of standing water, enough to cause minor flooding of roads, especially in poor drainage locations; <6 inches of fast flowing water across roads; or Arroyos/streams/creeks nearing bankfull, or briefly overtopping banks, producing < 6 inches of fast flowing water.|
|Snow [Squall Warning]||Medium violet red||Snow squall warning is a bulletin issued by he National Weather Service in the United States to warn population of two types of snow events reducing visibility in blowing snow: Lake effect snow squalls and Frontal snow squalls. Criteria for the National Weather Service to issue a Snow squall warning: Visibility of less than one quarter of a mile, sub-freezing temperatures on the ground, expected to last in one area less than 60 minutes, and may cause dangerous and life-threatening conditions.|
|(Storm Surge) Warning||SSWarning||Localized heavy flooding due to storm surge caused by a tropical cyclone is occurring or is imminent in the next 12 hours, which poses a threat to life and/or property.|
|Brisk W[ind Advisory]||Thistle||A Small Craft Advisory issued by the National Weather Service for ice-covered waters.|
|[Lake Effect Snow] Watch||Light sky blue||Significant amounts of lake-effect snow (generally 6 inches within 12 hours or 8 inches within 24 hours) are possible in the next 12 to 48 hours.|
|Coastal Fl[ood Advisory]||Lawn green||Minor coastal flooding is occurring or is imminent in the next 12 hours, which poses a threat to life and/or property.|
|Dense Smo[ke Advisory]||Khaki||Widespread or localized smoke reducing visibilities to 1⁄4 mi (0.4 km) or less.|
|[Severe Weather Sta]tement||Aqua||A National Weather Service product which provides follow up information on severe weather conditions (severe thunderstorm or tornadoes) which have occurred or are currently occurring.|
|[Lakeshore Flood] Advisory||Lawn green||Minor lakeshore flooding is occurring or is imminent in the next 12 hours, which poses a threat to life and/or property.|
|Wind Chill Ad[visory]||Pale turquoise||Dangerous wind chills making it feel very cold are imminent or occurring; the criteria varies significantly over different county warning areas.|
|Blizzard Warn[ing]||Orange red||Sustained winds or frequent gusts of 35 miles per hour (56 km/h) or greater, considerable falling, and/or blowing snow reducing visibility frequently to 1⁄4 mile (0.40 km) or less for a period of three hours or more. There are no temperature criteria in the definition of a blizzard, but freezing temperatures of at least 0 °C (32 °F) and 35 miles per hour (56 km/h) winds will create wind chills of at least −8.5 °C (16.7 °F).|
|Hurricane Warning||Crimson||A warning that sustained winds 64 kn (74 mph or 118 km/h) or higher associated with a hurricane are expected, and tropical storm conditions are expected within 36 hours in a specified area. A hurricane warning can remain in effect when dangerously high water or a combination of dangerously high water and exceptionally high waves continue, even though winds may be less than hurricane force (also automatically indicates a Tropical Storm Warning).|
|Extreme Fire [Danger]||Dark salmon||Fires start quickly, spread furiously, and burn intensely. All fires are potentially serious.|
|[Freezing Fog Adv]isory||Teal||Widespread dense fog reducing visibility to less than 1⁄4 mile (400 m) that occurs in a sub-zero environment, leaving a thin glazing of ice.|
|Tsunami Warning||Tomato||Warnings are issued due to the imminent threat of a tsunami from a large undersea earthquake or following confirmation that a potentially destructive tsunami is underway. They may initially be based only on seismic information as a means of providing the earliest possible alert.|
|Avalanche W[arning]||Dodger blue||A warning of current or imminent avalanche activity when avalanche danger is considered high or extreme. Authorized officials may recommend or order protective actions according to state law or local ordinance when natural or human-triggered avalanches are likely to affect roadways, structures, or backcountry activities.|
|Fire Warning||Sienna||A fire is currently burning in the area and evacuation is recommended.|
|Volcano Warn[ing]||Dark slate gray||A warning of current or imminent volcanic activity. Authorized officials may recommend or order protective actions according to state law or local ordinance.|
|Ashfall Advisory||Dim gray||Airborne ash plume resulting in an ongoing deposition at the surface. Ashfall may originate directly from a volcanic eruption or from the re-suspension (by wind) of a significant amount of relic ash.|
|Red Flag Warning||Deep pink||A red flag warning means that conditions are favorable for the rapid spread of wildfires. While there are very few areas immune to wildfires, one that encompasses the entire country would be unlikely unless a conflagration of epic magnitude swept through the country.|
|Radiological hazard warning||Indigo||A radiological hazard warning is a non-weather event that is transmitted by the NWS. This means that a radiological source was lost, discovered, or released accidentally or maliciously. If the entire country were under such a warning, the outlook for the citizens would be pretty grim.|
|Evacuation - Immediate||Chartreuse||Evacuation Immediate is a warning issued through the Emergency Alert System (EAS) in the United States to notify the public of a mandatory evacuation due to a wildfire, approaching hurricane, or an imminent explosion due to a gas leak.|
|Shelter In Place Warning||Salmon||Shelter In-Place Warning is to seek safety within the building one already occupies, rather than to evacuate the area or seek a community emergency shelter. The American Red Cross says the warning is issued when "chemical, biological, or radiological contaminants may be released accidentally or intentionally into the environment" and residents should "select a small, interior room, with no or few windows, taking refuge there."|
|911 Telephone Outage||Silver||An emergency message that defines a local or state 911 telephone network outage by geographic area or telephone exchange. Authorized officials may provide alternative phone numbers in which to reach 911 or dispatch personnel.|
