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.
