2005 Atlantic Hurricane Season (AGCK)

The 2005 Atlantic Hurricane Season ran from June 1, 2005 to November 30, 2005 but storms can form during anytime of the year, demonstrated by Hurricane Arlene and Tropical Storm Bret.

Hurricane Arlene
A tropical wave exited the coast of Cape Verde on May 15 and traveled on a westward track, with no initial deep convection as it eventually entered the Caribbean Sea, where it began to show more deep convection as the NHC noted this system with a 10% chance of development within 2 days and a 40% chance of development within 5 days. Eventually, as the SST's got warmer, the wave began to show more deep convection and it began to show a structure similar to a tropical cyclone, which caused the NHC to initiate advisories on Tropical Depression One at 18:00 UTC on May 19th. Tropical Depression One then intensified into Tropical Storm Arlene the next afternoon as wind shear gradually decreased as Arlene began to travel more up north as forecasters noted that this could possibly be a minimal hurricane at landfall as Arlene then began to intensify. By May 21st, a ragged pinhole eye was beginning to show in the system as Arlene reached 70 miles per hour; forecasters were now predicting this would at least peak as a strong category 1 hurricane or a minimal category 2 hurricane. Arlene then began to go into a rapid deepening phase on May 22nd as banding and organization got better as Arlene began to grow in size, eventually reaching 110 miles per hour as forecasters predicted it would maintain intensity until landfall; and that is what it did as it neared landfall, however the system began developing a bit more before landfall, eventually growing a large eyewall and reaching 115 miles per hour briefly on May 24th, becoming the most intense off-season storm on record, before weakening down to 110 miles per hour after maintaing peak intensity for 18 hours; the storm then made landfall as a 110 mile per hour hurricane; Arlene's structure rapidly deteoriated over land as the eye became clouded and the eyewall disappeared as it weakened steadily down from 110 miles per hour to 60 miles per hour in 36 hours; Arlene then turned extratropical on May 27th and remained like this for twelve hours before degrading and dissipating over land. Arlene caused $1.2 billion in damages and caused 57 fatalities; therefore Arlene was retired and replaced with Ally.

Tropical Storm Bret
A broad low pressure system developed to the north of the Bahamas on May 22 and quickly developed deep convection as showers and thunderstorms increased quickly, which caused advisories to be initiated only 18 hours later as the system became Tropical Depression Two as it began to move to the northeast as the Gulf Stream was fueling intensification as the system became Tropical Storm Bret later that day as rapid deepening began as banding got better and an extremely small eye that was clouded was inside the system; they later found that Bret intensified from 40mph to 60mph in less then 6 hours; however the Gulf Stream then began to let up as it refused to change direction, causing the structure to degrade instantly as the winds went down in the system as it turned into a depression by May 25th; it remained this way before it was considered dissipated. Bret caused no damage and no fatalities, therefore Bret was not retired.
