We're seeing an increase in atmospheric moisture across the east half of the viewing area this morning. This means we will have a better chance for rain today especially east of I-45.
Don is currently located just north of the Yucatan with max winds of 40mph and moving WNW at 10mph. It is forecast to make land fall on the middle to lower Texas coast around 1:AM Saturday morning with max winds near the center of 60mph. However, because Don is a very small storm it's forecast track and intensity may change quickly with very little notice. This means we need to monitor the storm very closely and be prepared for forecast changes.
What we need out of this storm is rain. The closer the storm gets to southeast Texas the greater our rainfall potential will be. However, if the storm stays well to our south then rain totals will be limited here. On its current track toward the middle Texas coast we should see widespread 1/2" totals here and more in some spots. Along and just to the right of the center of the storm they are expecting 2"-4" with some 6" totals.
