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

    DISCUSSION AND OUTLOOK
    ----------------------
    At 1000 PM CDT (0300 UTC), the center of Tropical Depression
    Nicholas was located near latitude 30.0 North, longitude 94.1 West.
    The depression is moving toward the east-northeast near 6 mph
    (9 km/h). A slow motion toward the east is expected tonight
    through Wednesday night, followed by a northward drift on Thursday.

    Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
    Continued gradual weakening is expected during the next couple of
    days, and Nicholas is forecast to degenerate into a remnant low
    Wednesday night or early Thursday.

    The minimum central pressure based on surface observations is
    1004 mb (29.65 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Nicholas can be found in the Tropical Cyclone
    Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC
    and on the web at hurricanes.gov/graphics_at4.shtml?key_messages

    RAINFALL: Nicholas is expected to produce additional rainfall
    amounts of 5 to 10 inches across portions of southern and central
    Louisiana, southern Mississippi, far southern Alabama, and the
    western Florida Panhandle through early Friday, with isolated storm
    totals of 20 inches possible from southern Louisiana to the far
    western Florida Panhandle. Life-threatening flash flooding impacts,
    especially in urban areas, are possible across these regions.

    Widespread minor to isolated moderate river flooding is expected
    across portions of the upper Texas Gulf Coast and southern Louisiana
    and Mississippi.

    For the latest rainfall reports and wind gusts associated with
    Tropical Storm Nicholas see the companion storm summary at WBCSCCNS4
    with the WMO header ACUS44KWBC or at the following link
    https://www.wpc.ncep.noaa.gov/discussions/nfdscc4.html

    STORM SURGE: Storm surge levels will gradually subside into this
    evening. For information specific to your area, please see
    products issued by your local National Weather Service forecast
    office.

    WIND: Wind gusts to tropical-storm force are possible for a few
    more hours along the Louisiana and upper Texas coasts. These
    conditions should diminish later tonight and Wednesday morning.

    TORNADOES: A tornado or two will be possible tonight through early
    morning from southeast Louisiana to southwest Alabama.

    SURF: Swells generated by Nicholas will continue affecting portions
    of the northwest Gulf coast this evening and gradually subside
    tonight. These swells are likely to cause life-threatening surf and
    rip current conditions. Please consult products from your
    local weather office.

    Tropical Depression Nicholas Discussion Number 12

    1000 PM CDT Tue Sep 14 2021

    Satellite imagery, radar data, and surface observation indicate
    that the center of Nicholas is over the Beaumont/Port Arthur area
    of southeastern Texas. The cyclone is currently comprised of a
    large swirl of low- to mid-level clouds and showers, with a few
    patches of deep convection well removed from the center. The
    initial intensity of 30 kt is based on a combination of Doppler
    radar data and surface obs, and these winds are mainly over water
    to the southeast of the center. Nicholas should continue to weaken
    due to strong shear, dry air entrainment, and land interaction,
    and the cyclone is forecast to degenerate to a remnant low after 24
    h and dissipate completely by 72 h. It should be noted that some
    of the track guidance models show enough south of east motion to
    bring the center back over the Gulf of Mexico in a day or two.
    However, even if this should occur the shear and dry air should
    prevent any re-development.

    The initial motion is 060/5. While there is some spread in the
    guidance, it generally agrees on a slow eastward motion for 36 h
    or so, followed by a northward drift. The new forecast track has
    only minor changes from the previous track.

    Although the winds associated with Nicholas are subsiding, due
    to the forecast slow motion, heavy rainfall and a significant flash
    flood risk will continue along the Gulf Coast for the next couple
    of days.

    The is the last advisory on Nicholas issued by the National
    Hurricane Center. Future information on this system can be found in
    Public Advisories issued by the Weather Prediction Center beginning
    at 4 AM CDT, under AWIPS header TCPAT4, WMO header WTNT34 KWNH, and
    on the web at http://www.wpc.ncep.noaa.gov.


    Key Messages:

    1. Heavy rainfall will impact areas across southern and central
    Louisiana, southern Mississippi, far southern Alabama, and the
    western Florida Panhandle through early Friday. Significant rainfall
    amounts are expected, potentially resulting in areas of
    life-threatening flash and urban flooding across these areas.
    Widespread minor to isolated moderate river flooding is also
    possible.

    2. Storm surge inundation along the coasts of upper Texas and
    southwestern Louisiana will diminish tonight.

    3. Wind gusts to tropical-storm force are possible for a few more
    hours along portion of the Louisiana and upper Texas coasts.
