Updated: 12pm ET Monday September 23, 2024 | From StormCenter Communications Weather Operations this is an update on Potential Tropical Cyclone Nine for the Sensitive Information Sharing Environment.
*Correction: Dave indicated this system could be the third hurricane this year to impact the big bend area of Florida. He meant to say the third hurricane in the last two years. (Idalia Aug 26-Aug 31, 2023 | Debby Aug 3-9, 2024). Helene would be the third in two years.
A tropical low pressure system s developing in the western Caribbean and is expected to develop into Hurricane Helene over the next day or two. This storm could become a HIGH IMPACT event for coastal Florida and well inland. Widespread impacts are possible and will become more evident as the system develops. Currently it is a broad area of low pressure but is expected to evolve rapidly and become potentially a major hurricane by Thursday morning or earlier.
KEY MESSAGES:
1. The disturbance is forecast to strengthen and be near hurricane
strength when it reaches the far northwestern Caribbean Sea Tuesday
night. Tropical storm conditions are expected over portions of
western Cuba and the northeastern coast of the Yucatan Peninsula
with hurricane conditions possible.
2. The system is expected to intensify while it moves northward
over the eastern Gulf of Mexico, and it could be a major hurricane
when it reaches the northeastern Gulf Coast on Thursday. There is an
increasing risk of life-threatening storm surge and damaging
hurricane-force winds along portions of the northern and
northeastern Gulf Coast, including the Florida Panhandle and
portions of the Florida west coast. Although it is too soon to
specify the exact location and magnitude of impacts, residents in
these areas should monitor the latest forecast updates and ensure
that they have their hurricane plan in place.
3. Potential Tropical Cyclone Nine will bring heavy rain to portions
of the western Caribbean which may lead to flooding and possible
mudslides in western Cuba.
