Tropical Storm Alberto (2018-Bob's Scenario)

Tropical Storm Alberto was the first tropical cyclone in the Gulf of Mexico during the month of May since 1976. The first named storm of the 2018 Atlantic hurricane season, Alberto formed from the interaction between a tropical wave and a Central American Gyre.

Meteorological History
On May 20, the National Hurricane Center (NHC) issued a Special Tropical Weather Outlook, giving a low chance of formation over the Northwestern Caribbean Sea within five days. Two days later, a broad area of low pressure formed after an interaction between a tropical wave and a Central American Gyre. At this point, the NHC gave the system a medium chance of development within 48 hours. The low pressure system slowly increased in organization during the next two days, but the convective activity remained poorly organized. At 18:00 UTC on May 23, an Air Force Hurricane Hunter aircraft investigated the system. The aircraft found that a broad center of circulation had developed, but not sufficiently well defined for the NHC to classify the system as a tropical cyclone. As a result, NHC initiated advisories on Potential Tropical Cyclone One at 21:00 UTC that day. Shortly afterward, an ASCAT-B pass indicated that the system was producing tropical storm force winds in its northeastern quadrant.

Early on May 24, a second reconnaissance aircraft investigated the system, and found that a single, though elongated low-level circulation had developed - prompting the NHC to upgrade the disturbance to a tropical storm. The NHC named the storm Alberto at this time, making it the first named storm of the 2018 Atlantic hurricane season. Alberto remained poorly organized, with the low-level center exposed to the west of a cluster of deep convection. However, the maximum sustained winds of the tropical storm increased to 60 miles per hour by 12:00 UTC on May 25. Immediately after this peak intensity, Alberto began to weaken as it moved over cooler waters in the northeastern Gulf of Mexico. Alberto made landfall over the Big Bend region of Florida at around 22:00 UTC that same day, as the convective activity of the system diminished. Shortly thereafter, Alberto began to take on extratropical characteristics. At 06:00 UTC on May 26, Alberto transitioned into an extratropical cyclone. The extratropical cyclone rapidly dissipated later that same day.
