2017 Atlantic midicane season

The 2017 Atlantic midicane season is an ongoing event in medicane formation. The season officially started on January 1st and will end on November 30th. The season has so far been below average, with 14 tropical depressions forming. Of these depressions, 12 have become tropical storms, 6 have become hurricanes, and only one has become a major hurricane. The season's first storm, Tropical Storm Adriana, developed at an unusually late time on May 31st.

Tropical Storm Adriana
A tropical wave entered the Gulf of Mexico on May 30th. Favorable conditions allowed the wave to organize, and it was designated as Potential Tropical Cyclone One later that day. By May 31st, convection had increased to an extent where the disturbance could be classified as Tropical Depression One. A CMC aircraft was sent to investigate the system at 17:00 EST. They found that the depression was producing wind speeds of 40 mph and that a well-defined core had developed. Thus, the CMC upgraded the depression to Tropical Storm Adriana.

Adriana tracked slowly across the Gulf of Mexico, strengthening gradually. By June 2nd, it had reached peak intensity with wind speeds of 50 mph (85 km/h) with a minimum pressure of 1003 mbar. The following day, Adriana made landfall in Veracruz, Mexico at peak intensity. Heavy rains from the system caused coastal flooding and triggered heavy mudslides in the mountainous regions. Entire villages were buried from mudslides and 7 people lost their lives. Adriana caused $170 million USD in damages. Weakening rapidly over land, the storm finally dissipated on June 3rd.

Tropical Storm Brett
A trough of low pressure formed in the southwest Caribbean Sea on June 29th. The large, monsoon-like system continued northward and was expected to strengthen. By June 30th, the disturbance had strengthened significantly, and the CMC sent the Midicane Hunters into the system to investigate. A warm core and wind speeds of 45 mph was reported, and the trough was classified as Tropical Storm Brett without already being classified as a tropical depression or potential tropical cyclone. Brett tracked north-northeast towards the Gulf Coast of the United States and continued to strengthen.
