2015 Atlantic hurricane season (Puffle's Version)

The 2015 Atlantic hurricane season is a current event in the annual tropical cyclone season in the northern hemisphere. The season officially begins on June 1, 2015 and end on November 30, 2015. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year. The first storm, Ana, developed a month before the official start of the season, becoming the first pre-season tropical cyclone since 2012's Tropical Storm Beryl.

Seasonal forecasts
Forecasts of hurricane activity are issued before each hurricane season by noted hurricane experts Philip J. Klotzbach, William M. Gray, and their associates at Colorado State University (CSU); and separately by National Oceanic and Atmospheric Administration (NOAA) forecasters.

Klotzbach's team (formerly led by Gray) defined the average number of storms per season (1981 to 2010) as 12.1 tropical storms, 6.4 hurricanes, 2.7 major hurricanes (storms reaching at least Category 3 strength on the Saffir–Simpson hurricane wind scale), and an Accumulated Cyclone Energy (ACE) index of 96.1. NOAA defines a season as above-normal, near-normal or below-normal by a combination of the number of named storms, the number reaching hurricane strength, the number reaching major hurricane strength, and the ACE index.

Pre-season forecasts
On December 9, 2014, Tropical Storm Risk (TSR), a public consortium consisting of experts on insurance, risk management, and seasonal climate forecasting at University College London, issued their first outlook on seasonal hurricane activity during the 2015 season. In their report, the organization forecast activity about 20% below the 1950–2014 average, or about 30% below the 2005–2014 average, totaling to 13 (±4) tropical storms, 6 (±3) hurricanes, 2 (±2) major hurricanes, and a cumulative ACE index of 79 (±58) units. This forecast was largely based on an enhancement of low-level trade winds across the tropical Atlantic during the July to September period. TSR's report stressed that uncertainty in this forecast existed due to the unpredictability in the El Niño Southern Oscillation and North Atlantic sea surface temperatures. A few months later, on April 9, 2015, the organization updated their report, detailing their prediction of activity 45% below the 1950–2014, or about 50% below the recent 2005–2014 average, with 11 named storms, 5 hurricanes, 2 major hurricanes, and a cumulative ACE index of 56 units. TSR cited what were expected to be cooler than average ocean temperatures across the tropical North Atlantic and Caribbean Sea as reasoning for lower activity. In addition, the report stated that if the ACE forecast for 2015 were to verify, the total values during the three-year period from 2013–2015 would be the lowest since 1992–1994, signalling a possible end to the active phase of Atlantic hurricane activity that began in 1995.

On April 9, CSU also released their first quantitative forecast for the 2015 hurricane season, predicting 7 named storms, 3 hurricanes, 1 major hurricane, and a cumulative ACE index of 40 units. The combination of cooler than average waters in the tropical and subtropical Atlantic, as well as a developing El Niño predicted to reach at least moderate intensity, were expected to favor one of the least active seasons since the mid-1990s. The probabilities of a major hurricane striking various coastal areas across the Atlantic were lower than average, although CSU stressed that it only takes one landfalling hurricane to make it an active season for residents involved. On April 13, North Carolina State University released their forecast, predicting a near record-low season with just four to six named storms, one to three hurricanes, and one major hurricane.

Seasonal summary
The Accumulated Cyclone Energy (ACE) for the season as of 03:00 UTC May 9 is 0.89 units.

Tropical Storm Ana
On May 3, the National Hurricane Center began highlighting the expected formation of a non-tropical area of low pressure north of the Bahamas later in the week. Early on May 6, a weak surface low was associated with a broad upper trough as disorganized shower and thunderstorm activity extended across Florida, The Bahamas, and adjacent waters. Steady development occurred over the warm waters of the Gulf Stream, and by 03:00 UTC on May 8, the disturbance acquired sufficient organization to be declared Subtropical Storm Ana. By May 9, Ana became fully tropical. Ana is the earliest forming tropical or subtropical cyclone in the Atlantic since Ana in April 2003. On May 9, Ana continued to intensify, and it transitioned from subtropical storm into tropical storm.

Current storm information
As of 8 a.m. EDT (12:00 UTC) May 9, Tropical Storm Ana is located within 15 nautical miles of 32.6°N, -77.8°W, about 105 mi south southeast of Cape Fear, North Carolina. Maximum sustained winds are 50 kn, with maximum gusts up to 60 kn. The minimum barometric pressure is 1001 mbar, and the system is currently moving north-northeast at 4 kn. Tropical storm-force winds extend outward up to 125 mi from the center of Ana.

Storm names
The following list of names will be used for named storms that form in the North Atlantic in 2015. Retired names, if any, will be announced by the World Meteorological Organization in the spring of 2016. The names not retired from this list will be used again in the 2021 season list. This is the same list used in the 2009 season. The name Joaquin replaced Juan after 2003, but was not used in 2009.

Season effects
This is a table of all of the storms that have formed during the 2015 Atlantic hurricane season. It includes their duration, names, landfall(s) (denoted by bold location names), damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2015 USD.
