    Subtropical Storm Alberto moving northward across the Gulf of Mexico

    5/27/2018 6:00:00 PM

    Subtropical Storm Alberto has not changed very much in organization this afternoon. Convection has wrapped around the southern edge of the center but dry air continues to erode away at the eastern and now the northern side of the storm, exposing the low-level center.

    Wind shear, or the change of speed and direction with height, has decreased slightly and will remain at low levels through tonight and into Monday. Alberto is traveling over warm water, which should help it complete the transition into a tropical storm later tonight or early Monday. By the time Alberto makes landfall late Monday morning over the Florida Panhandle, it is expected to be a tropical storm. The only concern is the amount of dry air that is being pulled into the system. This has and may continue to prevent significant thunderstorm development from occurring which will limit how much Alberto is able to strengthen.

    Alberto will bring life-threatening conditions to a large area through early this upcoming week. Heavy rainfall will spread northward across much of the Deep South through Tuesday. Flooding will be a concern across Florida, the Gulf Coast and the Deep South, especially near and east of Alberto's track. Localized rainfall amounts of 8 to 12 inches are expected in this area, which will lead to widespread flooding. Impassible roads and washouts, as well as flooded homes can be expected. Heavy rain and the threat for isolated flooding will follow Alberto's track northward into the Ohio Valley later in the week.

    In addition to flooding rainfall, coastal flooding will be possible with Alberto through Monday. An inundation of 1 to 3 feet is expected along Florida's gulf coast as the storm's forward motion slows near landfall. Also, Alberto will bring life-threatening rip currents to most of the Gulf Coast, especially east of the track through early this week. This is not good news for people who were planning on heading to the beach for Memorial Day weekend.

    As Alberto continues northward this evening, the outer rain bands may bring wind gusts up to 40-45 mph to the west coast of Florida along with a threat for isolated tornadoes and waterspouts.

    The threat for damaging winds with Alberto will be greatest near and east of the track as it comes onshore late Monday morning. Sustained winds of 50-60 mph and gusts of 65-75 mph along the immediate coastline will cause power outages and some tree and structural damage.

    Aside from Alberto, there are no other features worth watching at this time in the Atlantic Basin.
