Early today Tropical Depression Two-E was upgraded to tropical storm Aletta. This is the first tropical storm of the 2018 eastern North Pacific season. Aletta was located well southwest of Mexico. The National Hurricane Center (NHC) predicts that Aletta will become a hurricane tomorrow as it moves westward over the open waters of the eastern North Pacific ocean. The GPM core observatory satellite passed above developing tropical storm Aletta on June 6, 2018 at 0046 UTC.

The first cyclone to strike the area, Sagar, formed from an area of thunderstorm activity located in the western Arabian Sea south of the island of Socatra. The area of low pressure associated with the thunderstorms first moved northwest into the far eastern Gulf of Aden, where it intensified into a minimal tropical storm with sustained winds estimated at 35 knots (~40 mph) by the Joint Typhoon Warning Center (JTWC), before turning west and then southwest down the middle of the Gulf. As it moved down the Gulf, Sagar slowly strengthened into a stronger tropical storm with sustained winds

Alberto formed out of a broad area of low pressure at the surface that was located over and around the Yucatan Peninsula. Because the area of low pressure was under the influence of a nearby upper-level trough, Alberto was designated as a subtropical storm by the National Hurricane Center (NHC) on the morning of Friday May 25th, which is rather unusual as most subtropical storms form at higher latitudes. The storm initially formed just east of the Yucatan Peninsula. A large subtropical ridge over the southwestern Atlantic steered Alberto on a northward track, and the storm brushed the far
