TS 1 - forms July 9th off the east coast of the United States, likely from a frontal or non-tropical disturbance. It moves northeastward ahead of a trough, likely moving through Atlantic Canada while extratropical. The date is key, because there are a great deal of June tropical storms with similar tracks affecting the southeastern United States from the Gulf of Mexico, but because it's July, the synoptic patterns are different. Examples include Barry 95, Bill 97, Arthur 2002, Beryl/TS3 2006 Cristobal 2008, Bret 2011, Claudette 2015. Arthur 2014 is a dangerous example of this storm, unexpectedly strengthening into a hurricane before hitting Cape Hatteras.
TS 2 - August 1 between Cape Verde and the Lesser Antilles from a tropical wave. The first storm in the Cape-Verde season to get going, but conditions are never very favorable. Examples include Alex 98, Chris 00, Durian/Erin 2013, Danny 2015. If the conditions are right though, this could be a major hurricane, and end up being more like H3.
H 3 - August 13 between Cape Verde and the Lesser Antilles from a tropical wave. If TS 2 developed in the mean development region, there's a good chance there could be a hurricane following soon after. Connie/Diane 55, Dean 89, Felix 95, Edouard 96, Bonnie 98, Cindy 99, Bill 09 are just a few examples of what this hurricane could become, and some have been landfalling major hurricanes in the United States. As statistically there are only 2 major hurricanes, and both develop later in the season, this is considered to be a Category 2 hurricane.
TS 4 - forms August 23rd in the southern Gulf of Mexico from tropical wave, likely in the Bay of Campeche. Typically, conditions are near ideal, but limited time over water prevents significant development, and the storm dissipates over Mexico. Examples include include TS 3 in 1946, Beryl 00, Bret/Gert/Jose in 2005, Dolly 2015. Bret 1999 is a worst-case scenario, as it moved northward instead of northwestward, so it became a C4 and struck Texas.
MH 5 - forms August 31 in the Caribbean from tropical wave, somewhere south of Puerto Rico to south of Cuba. Conditions can be rough, or very favorable, each year and track is different. There are a number of different scenarios from this storm. Felix 07 hit Nicaragua as a C5, having formed south of Cuba. Gustav 2008 struck Haiti and Cuba and ultimately hit Louisiana. Irene 2011 developed near Puerto Rico and ultimately struck North Carolina, becoming a major. Statistically the likeliest storm to cause the most damage and be retired.
TS 6 - September 8 in the western Atlantic Ocean from non-tropical origins. With such activity lately in the tropics, it's unlikely conditions will remain favorable down there, so there will likely be a storm crop up farther north. Examples include Gustav 02, Gabrielle 07, Unnamed 2011, Henri 15. Unlikely to strike the United States
H 7 - one last Cape Verde storm, forming on September 16. This could be an Isabel 03 type of storm, which hits North Carolina, a long tracker like Igor 2010 that hit Bermuda and Canada, or hit the eastern Caribbean Islands like Marilyn 95 (or do all of the above and be like Hugo 89 or Gloria 85). Plenty of danger potential. Consider it a Category 2 hurricane for the purposes of averages.
H 8 - similar to TS 6, forming on September 24 in the western Atlantic Ocean, possibly from non-tropical origins. A trough will almost inevitably bring it northward, but if it goes more to the west, it could affect land, like Joaquin 15 for the Bahamas. It could also go to the north like Karen 01 or Juan 03. Or be the fourth longest-lasting storm on record, like Kyle 02.
MH 9 - forms October 4 from a tropical wave east or near the Lesser Antilles. Bermuda has sometimes faced the brunt of this late-season storm, such as Otto 10, Gonzalo 14. It could also just affect the northeastern Lesser Antilles, like Omar 08 or Rafael 12.
TS 10 - develops on October 19, one final Gulf of Mexico storm. The storm likely has difficulty developing, and it remains weak due to the time of year. Examples include Stan 05 (which killed 2,000), Marco 08, or Karen 13. Sometimes it is more to the south, like Paula/Richard 10 or Rina 11, and even Wilma 05 for this time of year.
H 11 - forming in the Caribbean Sea on November 23, one last hurrah for hurricane trackers. Could strike Central America if a ridge is strong, like Gamma 05 or Ida 09, or it could be drawn more northward like Katrina 81, Karen 89, Marco 96, Michelle 01, or Paloma 08. Lenny 99 is a worst-case scenario of this storm, which was nearly a C4 and moved eastward, striking the northeastern Caribbean.
