This resulted in continuation of the spring weather pattern over the Atlantic Ocean, with strong vertical wind shear, mid-level moisture, and atmospheric stability, which suppressed tropical cyclogenesis.

[11] In June, predictions from CSU and TSR were similar to pre-season forecasts due to the a lack of an El Niño and warmer-than-average sea surface temperatures across the Atlantic Ocean.

[12][13] However, by July and August, CSU and TSR all adjusted their forecasts downward because of predictions of cooler-than-average sea surface temperatures and above-average wind shear.

[14][15] NOAA also decreased the amount of activity in its final outlook, despite predicting a wetter-than-average western Africa and above-average sea surface temperatures in its report.

This resulted in a continuation of the spring weather pattern over the Atlantic Ocean, with strong vertical wind shear, reduced mid-tropospheric moisture, and high atmospheric stability.

Despite strong wind shear and an abundance of dry air, the storm strengthened while initially heading north-northeastward, before turning northeastward later that day.

In Cuba, the storm brought flooding, with over 1,000 people fleeing their homes, mainly along the Cuyaguateje River in Pinar del Río Province.

[27] The remnants of Andrea brought gusty winds to Atlantic Canada, causing thousands of power outages in Nova Scotia and New Brunswick.

[32] The low later re-emerged into the Caribbean Sea and developed into a tropical depression at 12:00 UTC on June 17, while situated 60 mi (97 km) east of Monkey River Town.

Scatterometer passes indicating a closed circulation confirmed that Tropical Storm Chantal had developed by 12:00 UTC on July 7, while located about 1,250 mi (2,010 km) east-southeast of Barbados.

[38] In the Dominican Republic, a firefighter from the community of Maimon was killed as he was swept away by flood waters while attempting to clear a clogged storm drain.

[36] Chantal's remnant moisture interacted with a surface boundary over northeastern Florida, contributing to widespread thunderstorms that produced locally heavy rainfall and gusty winds.

At the time, the depression was situated about 70 mi (110 km) south of Praia, Cape Verde, prompting the issuance of tropical storm warnings for the southernmost islands.

The remnants proceeded westward on the low-level trade winds before opening up into a trough early on August 20, and ultimately dissipated several days later.

Warnings were canceled north of Barra de Nautla, Veracruz state early on August 26, and discontinued entirely after Fernand weakened to a tropical depression.

After the storm, Veracruz governor Javier Duarte declared a state of emergency for 92 municipalities, which allowed farmers who sustained damage to receive aid.

An increase in deep convection on September 6 led to the formation of a tropical depression by 12:00 UTC, located approximately 30 mi (48 km) east-northeast of Tampico, Mexico.

Despite moderate wind shear, Humberto continued to strengthen while passing south of Cape Verde, due to a moist atmosphere and warm ocean temperatures.

By late on September 12, increasing wind shear, cooling sea surface temperatures, and a more stable atmosphere led to a weakening trend of the storm.

Around 12:00 UTC on the next day, Humberto fell to tropical storm intensity, while curving west-northwestward in the low-level flow south of the Azores surface high pressure.

[64] Ingrid struck shortly after Hurricane Manuel on Mexico's Pacific coast, creating the first instance of two landfalling tropical cyclones in the nation within the same 24-hour period since 1958.

[65] Relief agencies distributed food and other aid to the hardest hit areas,[69][70] though in Tamaulipas, residents had to rely on assistance from the local Gulf Cartel.

Interaction with a mid- to upper-level low pressure forced the wave to split, with the southern portion spawning Tropical Storm Octave in the eastern Pacific Ocean on October 12.

At 00:00 UTC on October 1, Jerry attained its peak intensity with sustained winds of 50 mph (80 km/h) and a minimum barometric pressure of 1,005 mbar (29.7 inHg).

While the storm was threatening the Gulf Coast of the United States, the NHC issued several tropical cyclone warnings and watches as Karen approached.

[74] The mayor of the town of Grand Isle, Louisiana evacuated the island on October 4, while residents were also ordered to flee Lafourche and Plaquemines parishes.

Additionally, the moisture associated with the remnants of Karen was absorbed into a frontal system and caused minor flooding in a few states, including Delaware, Georgia, New Jersey, and Pennsylvania.

Amid colder ocean temperatures, Melissa lost all of its deep convection and transitioned into an extratropical cyclone at 00:00 UTC on November 22, at about 140 mi (230 km) north-northeast of Flores Island, Azores.

The cyclone then completed a counter-clockwise loop in response to the blocking area of high pressure to its north that would have otherwise caused the storm to move towards mainland Europe.

However, the National Hurricane Center did not initiate advisories, particularly due to predictions of stronger wind shear and decreasing sea surface temperatures preventing additional development.
