Winter Weather Alert Flags system described. Allison in the forecast?

By: JonahWitDaForecast , 2:13 PM GMT on October 28, 2011

To go with the fact that winter storms are named like hurricanes and categorized like hurricanes, now they have warning flags like hurricanes. Simply put, here it is.

WINTER WEATHER ADVISORY (WW-A) or FREEZING RAIN ADVISORY (FZR-A)


WINTER STORM WATCH (WS-WA)




WINTER STORM WARNING (WS-W)


BLIZZARD WATCH (BZ-WA)




BLIZZARD WATCH (BZ-WA) with WINTER STORM WARNING (WS-W)




BLIZZARD WARNING (BZ-W)




ICE STORM WATCH (ICE-W)


ICE STORM WATCH (ICE-W) with WINTER STORM WARNING (WS-W)




ICE STORM WARNING (ICE-W)




That's it. the whole system. While we're on the subject of winter storms, there's a nasty one which may develop and strike the coastal northeast this weekend. if it reaches sufficient organization and surpasses Lv.1 criteria, this storm could be determined worthy of a name and, if so, it would be Winter Storm ALLISON. as of this moment, it will certainly be numbered and so has been designated Winter Disturbance ONE. (1WDN). WD1 will be a Nor'easter. The entire coastal Northeast has been place under a Winter Weather Advisory (hereafter WWA to save time) and a winter storm watch by the DCWS. Should this system in fact become a named storm, the WWA would be upgraded to a Winter Storm Warning (hereafter WSW). The difference between a WWA and a WSW is that a WSW has higher criteria and indicates a greater threat of damage, disruption, and/or injury. More on Winter Disturbance ONE to come.
