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 2021 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

    ...PETER EXPECTED TO BECOME A REMNANT LOW SOON...


    SUMMARY OF 500 PM AST...2100 UTC...INFORMATION
    ----------------------------------------------
    LOCATION...21.7N 66.7W
    ABOUT 230 MI...370 KM N OF SAN JUAN PUERTO RICO
    MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H
    PRESENT MOVEMENT...NNW OR 340 DEGREES AT 5 MPH...7 KM/H
    MINIMUM CENTRAL PRESSURE...1008 MB...29.77 INCHES


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


    DISCUSSION AND OUTLOOK
    ----------------------
    At 500 PM AST (2100 UTC), the center of Tropical Depression Peter
    was located near latitude 21.7 North, longitude 66.7 West. The
    depression is moving toward the north-northwest near 5 mph (7
    km/h). A similar motion with gradual turn to the north is expected
    tonight followed by a turn toward the north-northeast tomorrow.

    Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
    Gradual weakening is expected during the next couple of days, and
    Peter is forecast to degenerate into a remnant low tonight or
    tomorrow.

    The estimated minimum central pressure is 1008 mb (29.77 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    SURF: Swells generated by Peter are affecting the Virgin Islands,
    Puerto Rico, and Hispaniola, and will continue spreading westward to
    the Bahamas tonight. These swells could cause life-threatening surf
    and rip current conditions. Please consult products from your local
    weather office.

    -------------
    Next complete advisory at 1100 PM AST.

NHC Discussion on Iota

    Tropical Depression Peter Discussion Number 17
    NWS National Hurricane Center Miami FL AL162021
    500 PM AST Wed Sep 22 2021

    Peter continues to just barely maintain its classification as a
    tropical cyclone. While the low-level circulation has remained
    intact today, the convection continues to be located well downshear
    to the east. However, there have been a few convective elements
    forming a bit closer to the center recently and that is the
    primarily justification for maintaining advisories on Peter as
    a tropical cyclone this afternoon. The initial intensity is
    maintained at 30 kt given the earlier scatterometer data, though
    this might be generous. Continued strong southwesterly vertical wind
    shear within a dry mid-level environment should ultimately strip the
    remaining convection away from Peter, with the tropical cyclone
    expected to finally peter out as a post-tropical remnant low in the
    next 12 hours.

    The depression has been moving very slowly recently, with an
    estimated north-northwestward motion of 340/4 kt. The cyclone is
    expected to turn northward and then north-northeastward following a
    weakness in the low-level ridge until the system finally opens up
    into a trough, sometime in the 48 to 60 hour period.
