Tropical Storm Aletta To Quickly Weaken in Midst of Dry Jet Stream

This image is from the ADT agency, or Advanced Dvorak Technique, from the CIMSS Tropical Cyclone tracking page. In the red and blue boxes, we have the center of the system. Notice the convection still ongoing around the front flank of the system. These storms should quickly dissipate as they approach and are sucked into the jet stream. The track continus to call for a general west northwestward direction before a turn to the north and eventually northeast as the jet stream takes hold.

Tropical Storm Aletta Shifts Out to Sea; New Development Possible

Tropical Storm Aletta is currently moving westward in the middle of the Pacific Ocean, far west of Mexico, pretty much in the middle of nowhere. Winds are sustained at a fair 45 MPH, making for a moderately weak tropical storm. The system is expected to fade out as the westward movement continues, with an eventual turn to the north, before the system becomes post-tropical.

And of course, because the East Pacific needs more storms than the Atlantic (which should be achievable with the now-dead La Nina), we have an area of potential development over the next several days. While it is at 10% now, the National Hurricane Center has indicated that development appears possible over the next several days.

And lastly, we have an area of weak showers drifting around in the far northeast Atlantic. Yes, there is a circulation judging by visible clouds, but there is also a patch of tightly wrapped showers within the system. Needless to say, there is a 0% chance for development as it isn't even classified as an invest at this point.
