Don remains rather elongated with most of the northwestern sector exposed to the elements. This is due to some upper level shear and drier air ahead of it. It now appears this shear will keep Don in check until it moves on shore without further intensification. Rainfall totals are forecast to be between 3-5 inches with some areas getting as much as seven. This is just what the doctor ordered since the region is under an extreme drought.
Watches and warnings have been issued mainly for Southern Texas.
