NHC Issues Hurricane Helene Tropical Cyclone Report

NHC Issues Hurricane Helene Tropical Cyclone Report

Timeline of Hurricane Helene (September 24-27, 2024)

  • September 20-22: A Central American Gyre (CAG) develops, bringing heavy rains to portions of Nicaragua and Honduras as it moves slowly northward.
  • September 23, 1200 UTC: The large circulation of the CAG straddles Central America and the northwestern Caribbean Sea. Deep convection begins to organize near a mid-level vorticity maximum about 130 nautical miles south of Grand Cayman. The system lacks a well-defined low-level center necessary to be a tropical cyclone.
  • September 23, 1500 UTC: The National Hurricane Center (NHC) initiates potential tropical cyclone advisories as the system is expected to become a tropical cyclone and bring tropical storm conditions to land areas within the next couple of days.
  • September 24: The system becomes Tropical Storm Helene. It enters the Gulf of America as a category 1 hurricane later in the day and turns northward.
  • September 25: Tropical storm conditions are observed over portions of the eastern Yucatan Peninsula of Mexico (including Cancun, Cozumel, and Isla Mujeres) and western Cuba. Helene develops a secondary wind maximum farther from the center.
  • September 26: Helene rapidly intensifies over the very warm Gulf waters while accelerating north-northeastward. Aircraft reconnaissance reports an eye around 0600 UTC, and a clear eye becomes visible on satellite imagery around 1800 UTC.
  • September 26, 1800 UTC: Helene intensifies into a 105-knot major hurricane, located about 150 nautical miles west-southwest of Tampa, Florida.
  • September 27, 0000 UTC: Helene reaches its peak intensity of 120 knots, located about 80 nautical miles south-southwest of the coast of the Florida Big Bend region. Its central pressure is estimated to be around 941 mb.
  • September 27, 0310 UTC: Hurricane Helene, a category 4 hurricane with winds of 120 knots and a central pressure of 939 mb, makes landfall about 10 nautical miles southwest of Perry, Florida. This is the strongest landfalling hurricane in the Florida Big Bend region since reliable records began around 1900.
  • September 27: Helene moves inland, bringing catastrophic storm surge to Florida's Gulf Coast, life-threatening wind gusts far inland across the southeastern United States, and historic rainfall leading to catastrophic flooding and landslides in the southern Appalachians. Numerous tornadoes are produced.
  • September 28, 0600 UTC: Helene's sustained winds drop below gale force.
  • September 28-29: The remnants of Helene continue to produce impacts, including tropical storm force winds and gusts across portions of the Mid-Atlantic and Ohio Valley as it becomes post-tropical and eventually dissipates.

Florida Expecting Impact from Hurricane Milton with Dangerous Storm Surge and 110 mph Winds

Florida Expecting Impact from Hurricane Milton with Dangerous Storm Surge and 110 mph Winds

Tropical Storm Milton is another rapidly developing tropical disturbance in the Gulf of Mexico that is expected to strengthen into Hurricane Milton and make landfall on the West Coast of Florida as a Category 2 hurricane around Wednesday. The forecast emphasizes the potential for significant storm surge and heavy rainfall, urging residents of Central and South Florida to stay informed and prepared. While the exact path and intensity of the storm are uncertain, remember that the effects can be for reaching from the center of the storm at landfall. There's also the increasing likelihood of a dangerous storm surge event along Florida's Gulf coast with some areas to be impacted already having been by hurricane Helene just a short time ago.

Growing Insurance Failures Take Spotlight After Hurricane Helene

Growing Insurance Failures Take Spotlight After Hurricane Helene

Hurricane Helene is a major disaster that highlights the growing economic risks associated with climate change. While the financial impact of the hurricane is significant, with estimates reaching over $100 billion with long-term implications for communities, businesses, and individuals. Climate change will increasingly lead to "known unknowns" - events that we know will happen but cannot predict their exact timing or location. Adaptation, investing in preventative measures, and the need for governments and companies to take proactive steps to mitigate the financial and social consequences of these events is vital to move forward.Suggested questions

Hurricane Helene’s Toxic Flood Waters

Hurricane Helene’s Toxic Flood Waters

There’s a hidden danger of toxic chemical releases from industrial facilities during hurricanes. Limited disclosure requirements and insufficient public information about these risks leave communities unprepared and unaware of the potential consequences. Red tide has been detected in Pinellas County waters following Hurricane Helene. This poses an additional health risk for residents already dealing with storm damage and cleanup, as red tide can cause respiratory problems and potentially harm marine life.

Hurricane Helene - HAARP Engineered and Steered to Wipe Out a Town

Hurricane Helene - HAARP Engineered and Steered to Wipe Out a Town

Conspiracy theories circulate about Hurricane Helene, which struck Florida in September 2024 and wreaked havoc upon upstate North Carolina. Some theories claim the hurricane was intentionally manipulated to impact Republican areas, while others suggest it was engineered to clear land for lithium mining. We also examine theories claiming the hurricane was created or guided by technology, such as HAARP, frequency transmitters, or cloud seeding. While lithium is on the mind of conspiracy theorist, a real life quartz mining facility has been severely impacted by Helene, which could cause supply chain disruptions for weeks or months.

Hurricane Ian: Investigation Shows Homeowners Insurance Companies Not Paying Up After 2 Years

Hurricane Ian: Investigation Shows Homeowners Insurance Companies Not Paying Up After 2 Years

A 60 Minutes report on insurer fraud in Florida following Hurricane Ian shows that numerous companies have systematically changed reports in order to deny homeowners of up to 90% of the payment they deserve after catastrophic losses. It focuses on the claims of several licensed adjusters, who allege that insurance carriers were purposefully altering damage reports to reduce payouts to homeowners. These adjusters claim that their reports were edited by desk adjusters who had never even visited the damaged properties, reducing the amount of money the homeowners received. The report alleges that this practice was widespread, affecting many homeowners who were left with significant damage and insufficient funds to repair their homes… and are still awaiting justice even today. While these charges have been presented to the Florida Attorney General’s office, they have failed to prosecute 2 years after Ian struck Southwest Florida in 2022.

Asheville - Climate Change “Safe Haven”?

Asheville - Climate Change “Safe Haven”?

We explore the devastating floods that hit Asheville, North Carolina, after Hurricane Helene, challenging the city's former reputation as a "climate haven." It explains that climate change is making intense rainfall events more frequent and severe, leaving even high-elevation areas vulnerable. Climate change is exacerbating flooding risks across the United States, including in Appalachia, where the terrain amplifies the impact of heavy rains. We also compare the recent floods to the "Great Flood" of 1916, highlighting the catastrophic devastation caused by heavy rainfall and emphasizing the historical context of similar events in the region. Damage from Helene is extensive, causing significant problems with infrastructure and prompting relief efforts as the full extent of the impact still remains unknown.
