On July 4, TSR released their fourth forecast for the season, increasing their predicted numbers to 17 named storms, 7 hurricanes, and 3 major hurricanes, due to the fact that El Niño conditions would no longer develop by the peak of the season and the warming of sea-surface temperatures across the basin. Prior to affecting the U.S. mainland, Miami’s mayor Tomás Regalado noted on Hurricane Irma, "This is the time to talk about climate change.

Selected pressure observations and best track minimum central pressure curve for . , Two people drowned due to strong rip currents produced by the hurricane: one in the Outer Banks of North Carolina and the other in Nantucket, Massachusetts. Along the coastline of the mainland United States, tropical storm-force gusts cut power to hundreds of citizens; rip currents offshore led to four deaths and numerous water rescues.

As it started on a northerly track, Rina continued to strengthen despite strong shear and dry air intrusion, and also began to show subtropical characteristics marked by most of the deep convection and strongest winds well removed from the center. Cindy reached tropical storm strength on June 20 th in the Gulf of Mexico, south of Louisiana. The usage of the name "Don" in July garnered some attention relating to United States President Donald Trump.  Total damage from Emily was estimated to be near US$10 million.

Regardless, some outlets such as the Associated Press "poked fun" at the name and Trump. Despite an unfavorable environment, with ocean temperatures near 68 °F (20 °C) and moderate wind shear, convection coalesced near the ce… , Harvey originated from a tropical wave that emerged into the Atlantic from the west coast of Africa on August 12. The NHC upgraded the system to Tropical Storm Lee at 15:00 UTC on the next day, based on an increase in deep convection and an advanced scatterometer (ASCAT) pass which indicated that it was producing minimal tropical-storm-force winds. On the West Pacific, Tropical Storm Nanmadol (2017), Tropical Storm Talas (2017), Typhoon Noru (2017), Tropical Storm Kulap, Tropical Storm Sonca (2017), Tropical Storm Roke (Fabian), Typhoon Nesat (2017), Tropical Storm Haitang (Huaning) and Tropical Storm Nalgae formed.

Ophelia became the easternmost major hurricane on record in the Atlantic. In addition, tropical Atlantic Ocean temperatures—previously below average in months prior to the start of the season—underwent rapid warming by late May, providing lower sea level pressures, weaker trade winds, increased mid-level moisture, and all-around a more conducive environment for above-average activity.  A combination of reconnaissance data and surface observations from the Windward Islands indicated that Don opened up into a tropical wave around 12:00 UTC on July 18, as it entered the eastern Caribbean Sea.
