***** ALWAYS CHECK & RE-CHECK THE LATEST FORECAST & UPDATES! *****
REMEMBER WHEN A TROPICAL STORM OR HURRICANE IS APPROACHING: Taping windows is *NOT* helpful & will not keep glass from breaking.
Realize the forecast cone (ācone of uncertaintyā) is the average forecast error over a given time - out to 5 days - & *does not* indicate the width of the storm &/or damage that might occur.
The weak & disorganized area of low pressure over the Northeastern Gulf of Mexico was upgraded to tropical depression #2 Thu. afternoon & to [a very weak/borderline] tropical storm āArleneā Fri. afternoon & dissipated over the SE Gulf Saturday. There were no direct impacts to any land areas.
Elsewhere - there are disorganized clusters of tāstorms over the Central & Western Atlantic associated with upper level troughs but no tropical development is expected.

Water vapor loop shows pockets of dry air (dark blue) across portions of the Atlantic Basin along with a lot of āswirlsā (low pressure) along with ābandsā of higher moisture near & ahead of fronts....
June tropical cyclone origins:
Averages below based on climatology for the Atlantic Basin for June:
Wind shear:
Saharan dust spreads west each year from Africa by the prevailing winds (from east to west over the Atlantic). Dry air - yellow/orange/red/pink. Widespread dust is indicative of dry air that can impede the development of tropical cyclones. However, sometimes āwannaā beā waves will just wait until they get to the other side of - or away from - the plume then try to develop if other conditions are favorable. In my personal opinion, way too much is made about the presence of Saharan dust & how it relates to tropical cyclones. In any case, the peak of Saharan dust typically is in June & July.
2023 names..... āBretā is the first name on the Atlantic list (names are picked at random by the World Meteorological Organization... repeat every 6 years). Historic storms are retired [Florence & Michael in ā18... Dorian in ā19 & Laura, Eta & Iota in ā20, Ida in ā21 & Fiona & Ian in ā22]). In fact, this yearās list of names is rather infamous with āKatrinaā, āRitaā & āWilmaā retired from the ā05 list & āHarveyā, āIrmaā,āMariaā & āNateā from the ā17 list. The WMO decided - beginning in 2021 - that the Greek alphabet will be no longer used & instead there will be a supplemental list of names if the first list is exhausted (has only happened three times - 2005, 2020 & 2021). The naming of tropical cyclones began on a consistent basis in 1953. More on the history of naming tropical cyclones * here *.
