    The 2024 Atlantic Hurricane season is being forecasted on the high side from several reputable sources, the Gulf of Mexico is much warmer than usual as is the main development area of the North Atlantic which will add moisture and energy to storms. The Pacific is also transitioning to a La Nina which is usually more conducive to conditions more favourable for development.

    Forecasting Hurricanes from NOAA, for some explanations of what's involved.

    A potential tropical storm that is forecast to cause severe flooding regardless of if it fully develops or not with a 70% formation chance:

    Seven day forecast graphic NOAA

    "For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

    1. A large area of disturbed weather is located over Central America,
      the Yucatan Peninsula of Mexico, and the adjacent waters of the
      northwestern Caribbean Sea. A broad area of low pressure is
      forecast to form from this system over the southwestern Gulf of
      Mexico on Monday or Tuesday. Environmental conditions appear
      conducive for subsequent gradual development of the low, and a
      tropical depression or tropical storm could form by midweek while
      it moves slowly westward or west-northwestward.

    Regardless of development, several days of heavy rainfall are
    expected across portions of southern Mexico and Central America, and
    these rains are likely to cause life-threatening flooding and flash
    flooding. Locally heavy rainfall is also expected to spread over
    portions of the northwestern coast of the Gulf of Mexico by the
    middle of the week. In addition, gale warnings have been issued
    for portions of the Gulf of Mexico, and more information on these
    is available in High Seas Forecasts issued by the National Weather
    Service.

    • Formation chance through 48 hours...low...30 percent.
    • Formation chance through 7 days...high...70 percent."

    There's also a second disturbance with a current 30% formation chance.

    Tropical Storm Alberto has formed in the Gulf of Mexico and is having impacts hundreds of kilometers away from its centre with storm surge flooding as far away as Texas.

    NHC advisory 8A:

    LOCATION...22.2N 95.1W
    ABOUT 180 MI...290 KM E OF TAMPICO MEXICO
    ABOUT 295 MI...475 KM SSE OF BROWNSVILLE TEXAS
    MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H
    PRESENT MOVEMENT...W OR 270 DEGREES AT 9 MPH...15 KM/H
    MINIMUM CENTRAL PRESSURE...995 MB...29.39 INCHES
    
    Alberto is a large tropical storm, with tropical-storm-force winds
    extending outward up to 415 miles (665 km) north of the center.
    
    RAINFALL: Tropical Storm Alberto is expected to produce rainfall
    totals of 5 to 10 inches across northeast Mexico into South Texas.
    Maximum totals around 20 inches are possible across the higher
    terrain of the Mexican states of Coahuila, Nuevo Leon, and
    Tamaulipas. This rainfall will likely produce considerable flash and
    urban flooding along with new and renewed river flooding. Mudslides
    are also possible in areas of higher terrain across northeast
    Mexico.

    Tropical Storm Beryl has formed and is forecast to become a Hurricane shortly. There's a serious chance it gets to Major Hurricane strength. One to watch.

    https://www.nhc.noaa.gov/text/refresh/MIATCDAT2%2Bshtml/290836.shtml?

    1. Tropical Storm Beryl is expected to strengthen and be a hurricane
      when it reaches the Windward Islands late Sunday night or Monday,
      bringing a risk of heavy rainfall, hurricane-force winds, and
      dangerous storm surge and waves.
    2. A Hurricane Watch is now in effect for Barbados. Additional
      Hurricane and Tropical Storm Watches, and possibly Warnings, will
      likely be required for portions of the Windward and southern Leeward
      Islands later today.
    3. Interests in the central and western Caribbean should monitor the
      progress of this system. Users are reminded that there is large
      uncertainty at days 4 and 5 and to not focus on the specific
      details of the track or intensity forecast.

    FORECAST POSITIONS AND MAX WINDS

    First ever Cat 4 hurricane in June now. If it gears up to be a busy storm season I wonder how we will fare out. A brief look at the Atlantic sea temperature shows that it's still tracking around last year's very high temps but the anomalous heat is in the Gulf of Mexico and the Caribbean. The northern half is actually trending cooler so let's hope it pans out well for us

    earliest Cat 4 in June… madness… this is the current image from Ventusky

    @sryanbruen (or anyone) will/could this storm potentially impact the JS and it's positioning? I'm not familiar with the vagueries of Hurricanes

    Major Hurricane Beryl is just after undergoing an eyewall replacement cycle. The damage is likely to be severe for the islands near the core's path.

    USA Today has a summary of Beryl and the season start here.

    Beryl – a major hurricane with sustained winds of 150 mph and higher gusts – tore across the southerly end of the Windward Islands on Monday, leaving potentially catastrophic damage in its wake on the Grenadine Islands and Grenada. Its meteoric increase in wind speeds broke records over the weekend.

    "It's very impressive how many different superlatives there are for Beryl,"
    Sam Lillo, a meteorologist and software engineer for DTN Weather, told
    USA TODAY on Sunday. The first hurricane on record to reach major
    hurricane status before July 1, Beryl also surprised forecasters with
    its early season arrival, so far south in the Atlantic.

    On Sunday evening, a system that had been brewing for a couple of days in the
    northwestern Caribbean and southwestern Gulf of Mexico became Tropical Storm Chris as it approached a forecast landfall on the Mexican coast That puts the
    season weeks ahead of normal. In a typical year, the season doesn't
    produce three named storms until Aug. 3.

    From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch’.

    The upstream conditions in the Western Caribbean are very unfavourable in the next few days with increasing shear from upper level winds so the storm's structure looks like it's going to deteriorate notably with the visible eyewall disappearing and the whole lot getting lopsided and messy as it moves closer to Jamaica. NHC has it as an off shore CAT 2 by Wednesday evening our time. Still potential for real disruption and rain affects but nowhere near what it is now in terms of the powerful winds .



  • Moderators, Society & Culture Moderators Posts: 1,714 Mod ✭✭✭✭star gazer


    Beryl has strengthened to a Category 5 Hurricane. It's the earliest forming one on record. A very anxious wait for Jamaica as to it's exact track and how much it will weaken by, as forecasts are suggesting.

    Hurricane Beryl Intermediate Advisory Number 14A
    NWS National Hurricane Center Miami FL AL022024

    Why do some hurricanes like Beryl not veer north?

    Are there weather system elsewhere at the moment that are countering the Coriolis effect or is it due to something else?



  • Moderators, Society & Culture Moderators Posts: 1,714 Mod ✭✭✭✭star gazer


    The initial motion is a quick 285/19 kt.  A strong subtropical
    ridge centered over the southern United States will continue to
    steer Beryl west-northwestward to westward across the central and
    northwestern Caribbean for the next few days, and this motion
    should bring the center near Jamaica in 24-36 h and the Yucatan
    Peninsula of Mexico around 72 h.  After that, there is a significant
    spread in the track guidance when Beryl emerges into the
    southwestern Gulf of Mexico, due mainly to model differences in the
    strength and location of a break in the subtropical ridge over the
    southern United States.  Thus, there remains considerable
    uncertainty in the track forecast during the latter part of the
    forecast period.

    We haven't had a hurricane hit the US now for several years, thankfully sparing many lives. Are we naieve enough to think this is purely down to luck?!
