Tomas Develops Off Northeast South America

Tropical Storm Tomas is currently off of South America near 58 W/11N and there are two active storms in the Atlantic, continuing a very active season (top image). Current Tomas IR image is shown in the middle graphic. Shary is forecast to pull rapidly northeastward and become extra-tropical. However, Tomas is forecast to move into the Caribbean and strengthen into a hurricane (bottom graphic).
Locally, as the cutoff in the East Pacific opens up and moves rapidly toward the Four Corners tomorrow, we can expect some more gusty winds. NAM forecast indicates a long fetch at 700 mb into Arizona tomorrow from low-latitudes of the Eastern Pacific. However, precipitable water over the Pacific southwest of here is quite low., with higher PW confined to the southern half of the GoC.
