Florida Braces For Impact: Tracking Invest 98'S Path

In September 2022, meteorologists were tracking a tropical wave in the Atlantic, called Invest 98-L, which had a high chance of developing into a tropical depression or storm. At the time, it was unclear whether Invest 98-L would hit Florida, but meteorologists predicted that it could enter the Gulf of Mexico by mid-week and potentially impact the state. The system had a 90% chance of formation within the next two to five days, and computer models indicated that it could move towards the Gulf Coast of the United States. However, the exact trajectory and impact of Invest 98-L remained uncertain, and meteorologists advised residents to stay calm, stay aware of forecasts, and prepare hurricane supplies if necessary.

Invest 98L's path and potential impact on Florida

Invest 98L, a tropical disturbance in the Caribbean Sea, has a high chance of developing into a tropical depression or storm in the coming days. As of Thursday, 22 September 2022, it was located in the southeastern Caribbean Sea, just north of the Venezuelan coast, with an 80-90% chance of developing into a tropical depression within the next two to five days.

Path

The disturbance is forecast to move west-northwest across the eastern Caribbean Sea over the next couple of days, reaching the central Caribbean Sea by the weekend. While its path beyond this is uncertain, many computer models predict it will enter the Gulf of Mexico by the middle of next week. Some models suggest it could then impact Florida, but it is too early to know for sure.

Potential Impact

The National Hurricane Center has said that the environment is forecast to become more favourable for Invest 98L's development in a couple of days, and meteorologists expect a tropical depression to form at that time. Long-range forecast models suggest the disturbance could pose a threat to areas along the Gulf Coast and Florida Peninsula in the US late next week.

Preparations

While it is too soon to know exactly where Invest 98L will go and what areas could be impacted, meteorologists recommend that people with interests along the Gulf Coast or in Florida pay close attention to the forecast and stay aware of any updates.

The formation of Invest 98L

The NHC predicted that Invest 98L would likely develop into a tropical depression within the next day or so as it moved west-northwest across the Caribbean towards more favourable environmental conditions. Meteorologists anticipated the area south of Cuba to be conducive to the system's strengthening and organising over the weekend. They attributed this to warm waters, light winds in the upper levels of the atmosphere, and abundant energy in the region.

By September 23, Invest 98L had officially formed and was designated as Tropical Depression Nine. This formation allowed meteorologists to employ computer models and Hurricane Hunter aircraft to gather more accurate data and gain a better understanding of the system's trajectory. Despite the improved data, it was still too early to determine the exact path of Tropical Depression Nine once it entered the Gulf of Mexico.

The European model predicted that the storm would be pulled northward, towards the eastern Gulf of Mexico or across the Florida peninsula during the Tuesday or Wednesday time frame of the following week. Alternatively, if the storm missed this northward turn, it could continue tracking northwest into the central Gulf of Mexico, potentially impacting the coastal areas of Louisiana, Mississippi, Alabama, or the Florida Panhandle. A third possibility, considered less likely, was that the system would remain relatively weak and continue west towards the Yucatan Peninsula and Mexico's mainland.

Meteorologists' predictions and modelling

As of Thursday, September 22, 2022, Invest 98-L was located in the southeastern Caribbean Sea, just north of the Venezuelan coast. It has been producing stormy weather across the Windward Islands, northern Venezuela, and the ABC island chain (Aruba, Bonaire, and Curaçao). The disturbance is forecast to move west-northwest across the eastern Caribbean Sea and be over the central Caribbean Sea by the weekend.

Computer models and forecast models vary, but many predict that Invest 98-L will enter the Gulf of Mexico by the middle of next week. However, it is still too early to determine the exact path and impact of the system once it reaches the Gulf. Meteorologists will be monitoring its formation and subsequent data from computer models to gain a better understanding of its potential track.

The National Hurricane Center (NHC) has warned of an increasing risk of coastal flooding, tropical-storm-force winds, heavy rainfall, rough surf, and beach erosion along the southeastern United States coast, the Florida east coast, and portions of the central and northwestern Bahamas beginning in the early to middle part of the week. The NHC may issue tropical storm, hurricane, or storm surge watches for some areas as early as Monday.

Florida Governor Ron DeSantis has urged residents to prepare for potential impacts and review their disaster plans, emphasising the importance of staying informed about the forecast and potential trajectory of Invest 98-L.

Hurricane Hunter aircraft and their role in data collection

Hurricane Hunter aircraft play a crucial role in data collection by flying directly into hurricanes to gather valuable weather information. These aircraft, operated by organisations such as the United States Air Force Reserve's 53rd Weather Reconnaissance Squadron and the National Oceanic and Atmospheric Administration (NOAA), provide essential data that improves the accuracy of hurricane forecasts and enhances our understanding of storm processes.

The history of flying into hurricanes dates back to the early 20th century, with the first crewed flight into a hurricane taking place in 1943. Over time, the technology and techniques have evolved, improving the safety and effectiveness of these missions.

Today, Hurricane Hunter aircraft are equipped with advanced instrumentation to collect critical data. The aircraft fly into the eye of the hurricane multiple times per mission, at altitudes ranging from 500 feet to 10,000 feet. Onboard scientists deploy Global Positioning System (GPS) dropwindsondes, which continuously transmit measurements of pressure, humidity, temperature, wind direction, and speed as they fall towards the sea. This provides a detailed vertical profile of the storm's structure and intensity. Additionally, the aircraft's tail Doppler radar and lower fuselage radar systems offer a real-time, three-dimensional view of the storm, further aiding in understanding its behaviour.

The data collected by Hurricane Hunter aircraft is invaluable for meteorologists and researchers. It helps in forecasting hurricane tracks and intensity, predicting storm surges, and studying the effects of atmospheric phenomena such as El Niño. This information is crucial for the safety of people living in vulnerable coastal areas, as it enables more accurate predictions and potentially life-saving evacuations.

In addition to their data collection role, Hurricane Hunter aircraft also participate in research missions to advance our understanding of hurricanes and other tropical cyclones. These missions contribute to the development of improved forecast models and a deeper scientific knowledge of these powerful storms.

Overall, the role of Hurricane Hunter aircraft in data collection is indispensable. By braving the dangers of flying into hurricanes, these aircraft and their crews provide invaluable information that saves lives, protects property, and improves our understanding of one of nature's most destructive forces.

The potential strength of Invest 98L

The National Hurricane Center (NHC) has stated that upper-level winds are currently inhibiting the development of Invest 98L, but this is expected to change in a couple of days, increasing the likelihood of a tropical depression forming. Once a tropical depression forms, it can be classified as a tropical storm when it reaches wind speeds of 39-73 mph, and a hurricane when winds exceed 74 mph.

Computer models and meteorologists are closely monitoring Invest 98L, with some indicating that it could enter the Gulf of Mexico by the middle of next week. However, the exact trajectory and strength of the system are still uncertain. Acting NHC Director Jamie Rhome emphasised the difficulty in predicting the path of a system that has not yet formed: "The predictability of systems that haven't formed yet is very, very low... Until this system actually forms, becomes a well-defined named system, the ability of models, the ability of humans to predict where it is going to go is really, really low."

While it is too early to determine the exact strength and path of Invest 98L, meteorologists predict that it has the potential to develop into a large and powerful system. WGNO Chief Meteorologist Hank Allen stated, "I really think this is going to be one of those storms... it has all the makings of a system that really sort of 'bombs out'... in the Caribbean." Allen also emphasised the importance of staying calm, staying aware of the forecast, and ensuring hurricane supplies are prepared.
