Tropical Storm Ana

Tropical storm (SSHWS)
Hurricane Michael (2012) - New Ana2015stevetrack
DurationJune 28 – July 6
Peak intensity70 mph (110 km/h) (1-min)  989 mbar (hPa)
A tropical wave about 50 miles north of South America traveled in favorable conditions for only about 2 hours, explaining why NHC never issued the system as a disturbance, and became Tropical Depression One. Without wind shear or dry air for over 300 miles east of the storm and 86°F (30°C) waters, the storm became Tropical Storm Ana. Unfortunately, a large pocket of dry air formed north of Ana, causing what before was called "The Holy Grail of Intensifying" by NHC was now a dry storm destroyer. Ana managed to have 50 mph winds before falling to a tropical depression. TD Ana stalled and took a turn NE, issuing tropical storm watches for 500 miles of the Florida coast. The system managed to become a tropical storm again, but was very disorganized and was out of the warm water area. Ana made landfall in Florida with 60 mph winds and drowned 4 people who were trapped in a car. After passing through Florida, Ana hit peak intensity, 70 mph with 989 mbar pressure. It formed an eye, and moved slowly WNW, which is somewhat unusual for the area. As it trekked for several more days, barely avoiding land, Ana became an extratropical cyclone. She also affected Massachusetts and made landfall in Nova Scotia, but dissipated just after. After full evaluation, Ana killed 5 people (Four in Florida, 1 in Nova Scotia) and caused about $16.5 million in damage.

Tropical Depression Two

Tropical depression (SSHWS)
Genevieve Aug 1 2014 1200Z Two2015steve
DurationJuly 8 – July 11
Peak intensity35 mph (55 km/h) (1-min)  1004 mbar (hPa)
Tropical Depression Two formed on July 8, it was slow moving system, and lasted 3 days. It affected a few islands in the Caribbean, but caused no damage nor deaths.

Tropical Storm Bill

Tropical storm (SSHWS)
Bertha Aug 2 2014 1455Z Bill2015steve
DurationJuly 28 – August 2
Peak intensity60 mph (95 km/h) (1-min)  999 mbar (hPa)
A small area of low pressure formed into a disturbance. Hurricane Hunters a few days later said that the storm had wind speeds up to 45 mph, but was not rotating. However, the disturbance soon started to intensify and became Tropical Storm Bill. Almost the whole time Bill was a storm, it was affecting land. Bill made landfall in the Virgin Islands, causing little damage. Then the system made landfall in Puerto Rico. However, the storm nearly stalled, and was at the peak winds the storm had (60 mph). Bill finally passed the island after nearly 30 hours. Bill made a third landfall in the Dominican Republic, and made a second landfall on the island after crossing the Samana Bay. Bill weakened very quickly and became a post-tropical cyclone on August 2. Bill caused 22 deaths and $32.5 million in damage.
