Features noted yesterday have moved eastward and northeastward during past 24-hours. The upper-level trough that will move across the Southwest is currently at about 30 N 125 W - above is 1100 UTC water vapor image this morning. This feature has mostly some high-level cloudiness with it.
Meanwhile, the NHC has begun forecasts for a new tropical depression (EP-21), that is currently south of southern Mexico.- IR image of 21-E below is from 1145 UTC this morning. The first NHC forecast for this system is shown at the bottom. The depression is forecast to strengthen eventually to hurricane strength as it heads north toward 20 N west of Cabo Corrientes. The global models indicate that the northward advance will be blocked early next week and moisture associated with this system may primarily affect north-central Mexico and perhaps the Southern Plains.
Edited to add: Forgot to mention that if this disturbance becomes a names TS/hurricane it will be "Vance".
