By retired, we mean no future Atlantic Basin storm will use that name again. The name is retired when a particular tropical storm or hurricane is so deadly and/or damaging that future use might be considered insensitive or confusing. When that happens, a new name is chosen by a WMO committee that will be used every six years going forward. Isaias replaced Ike when that notorious 2008 hurricane name was retired.

Calgary saw 24.6 cm of snow on Sept. 29, 2019, an event that cancelled classes and knocked out power to communities across the region. Winnipeg saw the exact same amount of snow the day before Halloween in 1971. A coastal storm walloped Halifax with 38.6 cm of snow on Oct. 20, 1974, which still stands today as one of the city’s largest single-day snowfalls on record.

We have the maps you need to track all the systems ongoing in the Pacific and Atlantic below. Tracking the AtlanticTropical development areasSea surface temperatures Wind shear These are areas of strong wind shear, the difference in wind speed and direction with height, which are shown in purple. High wind shear is hostile to mature tropical cyclones and those trying to develop.(MORE: What is wind shear?)Get More of Our News on GoogleSet The Weather Company as a 'Preferred Source' to get quicker access to the news you value. Dry, dusty airAnother nemesis of tropical systems is dry air. In hurricane season, plumes of dust-laden air stream across the basin from Africa's Sahara Desert, as you can see in the map below. This sinking, dry air squelches thunderstorm development, the building blocks of tropical storms and hurricanes. So areas in the brown shading below are generally unfavorable for development. Atlantic tracks so far this seasonThese are the tracks of systems that were at least tropical or subtropical storms so far in the Atlantic Basin.

An October nor'easter is meandering off the Atlantic coast, where it will bring high surf, rip currents, coastal flooding and winds to parts of the East Coast for several days this week. The National Hurricane Center has highlighted it as an area to watch this week for the potential development of Josephine. However, regardless of whether we call this system a nor'easter or Josephine, the impacts will be the same. The bottom line: This system will bring dangerous conditions to the East Coast for multiple days this week.(MORE: What is a nor'easter?)ImpactsWhile we do not expect this storm to be as strong as the late September nor'easter, there will still be some impacts.

Coastal flood alerts are in effect for parts of coastal North Carolina, where anywhere from 1 to 4 feet of inundation is possible.
