Inače za ovu oluju je NHC po prvi puta (novost od ove sezone) počeo izdavati upozorenja i izvještaje u obliku PTS "Potential tropical cyclone"
Citat:
Potential Tropical Cyclone Two Advisory Number 1
NWS National Hurricane Center Miami FL AL022017
500 PM AST Sun Jun 18 2017

...TROPICAL STORM WARNING ISSUED FOR PORTIONS OF THE WINDWARD
ISLANDS...

ta će se praksa primjenjivati kad se nekom području (otok, kopno) približava sistem koji još nije TD ili TS

Istovremeno s imenovanjem oluje Bret, izdan je i novi PTS za sistem koji se razvija nad Meksičkim zaljevom
Citat:
Potential Tropical Cyclone Three Advisory Number 1
NWS National Hurricane Center Miami FL AL032017
400 PM CDT Mon Jun 19 2017

...TROPICAL STORM WARNING ISSUED FOR PART OF THE LOUISIANA COAST...


Citat:
The NWS now has the option to issue advisories, watches, and
warnings for disturbances that are not yet a tropical cyclone, but
which pose the threat of bringing tropical storm or hurricane
conditions to land areas within 48 hours. Under previous policy
this was not possible. These systems are known as Potential
Tropical Cyclones in advisory products and are numbered from the
same list as depressions. Because of the threat to the central
Gulf coast, advisories have been initiated on Potential Tropical
Cyclone Three and the appropriate watches/warnings have been issued.

tako da će sutra vrlo vjerojatno istovremeno biti dvije tropske oluje na Atlantiku, mislim da to u lipnju još nije zabilježeno

edit: ipak je , a i lani je bilo blizu

Citat:
Only three other times have two Atlantic storms existed at the same time during June since records began. The other years were 1909, 1959 and 1968, according to Dr. Phil Klotzbach, tropical meteorologist at Colorado State University.

Last year came close, with Tropical Storm Bonnie fading June 4 and Tropical Storm Colin forming June 5.
The snow comes down so fast and thick, you can actually watch it pile up, and you can even hear it

Bret je postavio i rekord,
najranija tropska oluja forimirana u tzv. MDR području (Main development region) - tropski Atlantik istočno od meridijana 70°W i južnije od paralele 20°N (obuhvaća istočni dio Karipskog mora i područje tropskog Atlantika od Antila do obala Afrike gdje nastaje većina oluja i uragana usred sezone)

Citat:
Tropical Storm Bret's formation on June 19 was in the so-called main development region (MDR) of the tropical Atlantic. The MDR of the Atlantic typically sees the vast majority of its activity during the height of the hurricane season – August into September.

The southeastern U.S. coast, Gulf of Mexico and the western Caribbean are usual breeding grounds for tropical storms in June. The map below of storm origins since 1950 shows Bret's far removal from where systems typically develop in June.

Bret is only the third known tropical storm to develop in the MDR region before July 1 in 167 years of records, according to Bob Henson of Weather Underground. Bret's naming on June 19 also marked the earliest a storm has formed in the MDR, beating Ana, which formed June 22, 1979.
