Track The Tropics has been the #1 source to track the tropics 24/7 since 2013! The main goal of the site is to bring all of the important links and graphics to ONE PLACE so you can keep up to date on any threats to land during the Atlantic Hurricane Season! Hurricane Season 2024 in the Atlantic starts on June 1st and ends on November 30th. Love Spaghetti Models? Well you've come to the right place!! Remember when you're preparing for a storm: Run from the water; hide from the wind!

Hurricane Season 101

The official Atlantic Basin Hurricane Season runs from June 1st to November 30th.

A tropical cyclone is a warm-core, low pressure system without any “front” attached. It develops over tropical or subtropical waters, and has an organized circulation. Depending upon location, tropical cyclones have different names around the world. The Tropical Cyclones we track in the Atlantic basin are called Tropical Depressions, Tropical Storms and Hurricanes!

Atlantic Basin Tropical Cyclones are classified as follows:

Tropical Depression: Organized system of clouds and thunderstorms with defined surface circulation and max sustained winds of 38 mph or less.

Tropical Storm: Organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds of 39-73 mph.

Hurricane: Intense tropical weather system of strong thunderstorms with a well-defined surface circulation. A Hurricane has max sustained winds of 74 mph or higher!

The difference between Tropical Storm and Hurricane Watches, Warnings, Advisories and Outlooks

Warnings:Listen closely to instructions from local officials on TV, radio, cell phones or other computers for instructions from local officials.Evacuate immediately if told to do so.

  • Storm Surge Warning: There is a danger of life-threatening inundation from rising water moving inland from the shoreline somewhere within the specified area. This is generally within 36 hours. If you are under a storm surge warning, check for evacuation orders from your local officials.
  • Hurricane Warning: Hurricane conditions (sustained winds of 74 mph or greater) are expected somewhere within the specified area. NHC issues a hurricane warning 36 hours in advance of tropical storm-force winds to give you time to complete your preparations. All preparations should be complete. Evacuate immediately if so ordered.
  • Tropical Storm Warning: Tropical storm conditions (sustained winds of 39 to 73 mph) are expected within your area within 36 hours.
  • Extreme Wind Warning: Extreme sustained winds of a major hurricane (115 mph or greater), usually associated with the eyewall, are expected to begin within an hour. Take immediate shelter in the interior portion of a well-built structure.

Please note that hurricane and tropical storm watches and warnings for winds on land as well as storm surge watches and warnings can be issued for storms that the NWS believes will become tropical cyclones but have not yet attained all of the characteristics of a tropical cyclone (i.e., a closed low-level circulation, sustained thunderstorm activity, etc.). In these cases, the forecast conditions on land warrant alerting the public. These storms are referred to as “potential tropical cyclones” by the NWS.
Hurricane, tropical storm, and storm surge watches and warnings can also be issued for storms that have lost some or all of their tropical cyclone characteristics, but continue to produce dangerous conditions. These storms are called “post-tropical cyclones” by the NWS.

Watches: Listen closely to instructions from local officials on TV, radio, cell phones or other computers for instructions from local officials. Evacuate if told to do so.

  • Storm Surge Watch: Storm here is a possibility of life-threatening inundation from rising water moving inland from the shoreline somewhere within the specified area, generally within 48 hours. If you are under a storm surge watch, check for evacuation orders from your local officials.
  • Hurricane Watch: Huriricane conditions (sustained winds of 74 mph or greater) are possible within your area. Because it may not be safe to prepare for a hurricane once winds reach tropical storm force, The NHC issues hurricane watches 48 hours before it anticipates tropical storm-force winds.
  • Tropical Storm Watch: Tropical storm conditions (sustained winds of 39 to 73 mph) are possible within the specified area within 48 hours.

Advisories:

  • Tropical Cyclone Public Advisory:The Tropical Cyclone Public Advisory contains a list of all current coastal watches and warnings associated with an ongoing or potential tropical cyclone, a post-tropical cyclone, or a subtropical cyclone. It also provides the cyclone position, maximum sustained winds, current motion, and a description of the hazards associated with the storm.
  • Tropical Cyclone Track Forecast Cone:This graphic shows areas under tropical storm and hurricane watches and warnings, the current position of the center of the storm, and its predicted track. Forecast uncertainty is conveyed on the graphic by a “cone” (white and stippled areas) drawn such that the center of the storm will remain within the cone about 60 to 70 percent of the time. Remember, the effects of a tropical cyclone can span hundreds of miles. Areas well outside of the cone often experience hazards such as tornadoes or inland flooding from heavy rain.

Outlooks:

  • Tropical Weather Outlook:The Tropical Weather Outlook is a discussion of significant areas of disturbed weather and their potential for development during the next 5 days. The Outlook includes a categorical forecast of the probability of tropical cyclone formation during the first 48 hours and during the entire 5-day forecast period. You can also find graphical versions of the 2-day and 5-day Outlook here

    ...LESLIE DEGENERATES INTO A TROUGH...
    ...THIS IS THE LAST NHC ADVISORY...


    SUMMARY OF 300 PM GMT...1500 UTC...INFORMATION
    ----------------------------------------------
    LOCATION...33.3N 43.4W
    ABOUT 975 MI...1570 KM WSW OF THE AZORES
    MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H
    PRESENT MOVEMENT...NE OR 50 DEGREES AT 31 MPH...50 KM/H
    MINIMUM CENTRAL PRESSURE...1000 MB...29.53 INCHES


    WATCHES AND WARNINGS
    --------------------
    There are no coastal watches or warnings in effect.


    DISCUSSION AND OUTLOOK
    ----------------------
    At 300 PM GMT (1500 UTC), the remnants of Leslie were located near
    latitude 33.3 North, longitude 43.4 West. The remnants are moving
    quickly toward the northeast near 31 mph (50 km/h). A gradual turn
    toward the east at a fast forward speed is expected starting
    tonight, with a continued eastward motion expected into early next
    week. The remnants of Leslie are expected to move over or very near
    the Azores Sunday and early Monday.

    Recent satellite-derived wind data indicate that Leslie has
    degenerated into a trough, but maximum sustained winds remain near
    50 mph (85 km/h) with higher gusts. The remnants of Leslie are
    expected to gradually weaken during the next couple of days.

    Tropical-storm-force winds extend outward up to 140 miles (220 km)
    from the center.

    The estimated minimum central pressure is 1000 mb (29.53 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    None.

NHC Discussion on Sam

    Remnants Of Leslie Discussion Number 41
    NWS National Hurricane Center Miami FL AL132024
    300 PM GMT Sat Oct 12 2024

    ASCAT-B data valid near 1300 UTC indicated that Leslie's fast
    forward motion has caused it to open into a trough. Therefore, this
    will be the last NHC advisory on Leslie. The ASCAT data indicated
    that winds of 40-45 kt are still present on the east side of
    Leslie's remnants, where it continues to produce limited deep
    convection.

    A mid-latitude frontal system is nearing the remnants of Leslie, and
    the two systems are expected to merge within the next 12 h or so,
    marking Leslie's full transition to a post-tropical cyclone. It is
    possible that Leslie will redevelop a closed circulation as a
    non-tropical low at that point. The cyclone is expected to turn
    eastward on Sunday, bringing it very near or over the Azores late
    Sunday and through early Monday. By Monday afternoon, Leslie's
    center is expected to become poorly defined again as it interacts
    with another weaker mid-latitude cyclone to the east of the Azores.

    Additional information on this system can be found in High Seas
    Forecasts issued by the National Weather Service, under AWIPS header
    NFDHSFAT1, WMO header FZNT01 KWBC, and online at
