/></a><figcaption>Storm warning flag (US)</figcaption></figure> <p>At sea, a <b>storm warning</b> is a warning issued by the <a href="/wiki/National_Weather_Service" title="National Weather Service">National Weather Service</a> of the <a href="/wiki/United_States" title="United States">United States</a> when winds between 48 knots (89 km/h, 55 mph) and 63 knots (117 km/h, 73 mph) are occurring or predicted to occur soon. The winds must not be associated with a tropical cyclone.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> If the winds are associated with a tropical cyclone, a <a href="/wiki/Tropical_storm_warning" class="mw-redirect" title="Tropical storm warning">tropical storm warning</a> will be substituted for the storm warning and less severe <a href="/wiki/Gale_warning" title="Gale warning">gale warning</a>. </p><p>In US maritime warning flag systems, a red square flag with a black square taking up the middle ninth of the flag is used to indicate a storm warning (the use of two such flags denotes a <a href="/wiki/Hurricane_force_wind_warning" title="Hurricane force wind warning">hurricane force wind warning</a> or a <a href="/wiki/Hurricane_Warning" class="mw-redirect" title="Hurricane Warning">hurricane warning</a>). The same flag as a storm warning is used to indicate a tropical storm warning. </p><p>On land, the National Weather Service issues a 'high wind warning' (Specific Area Message Encoding code: HWW) for storm-force winds, which also encompasses the lesser <a href="/wiki/Gale_warning" title="Gale warning">gale-force</a> and greater <a href="/wiki/Hurricane_force_wind_warning" title="Hurricane force wind warning">hurricane force</a> winds. In most cases, the warning applies to winds of 40-114 MPH for at least 1 hour; or any gusts of 58-114 miles per hour on land unless a tropical storm warning, blizzard warning, winter storm warning, severe thunderstorm warning, or dust storm warning covers the phenomenon. Winds in excess of 115 MPH (100 kt) will always result in new issuance of an <a href="/wiki/Extreme_wind_warning" title="Extreme wind warning">extreme wind warning</a> shortly before their onset, typically right before the <a href="/wiki/Eyewall" class="mw-redirect" title="Eyewall">eyewall</a> of a major <a href="/wiki/Hurricane" class="mw-redirect" title="Hurricane">hurricane</a> makes landfall, but possibly as a substitute for a <a href="/wiki/Severe_thunderstorm_warning" title="Severe thunderstorm warning">severe thunderstorm warning</a> in an extreme <a href="/wiki/Derecho" title="Derecho">derecho</a> event. The only exception is that if the extreme winds are associated with a tornado, a <a href="/wiki/Tornado_warning" title="Tornado warning">tornado warning</a> (or more likely a <a href="/wiki/Tornado_emergency" title="Tornado emergency">tornado emergency</a>) will be issued instead. </p><p><br /> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Weather_Warning_Flags_(United_States)"><span id="Weather_Warning_Flags_.28United_States.29"></span>Weather Warning Flags (United States)</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Storm_warning&action=edit&section=1" title="Edit section: Weather Warning Flags (United States)"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul class="gallery mw-gallery-traditional"> <li class="gallerybox" style="width: 155px"> <div class="thumb" style="width: 150px;
