Here's the 10 p.m. position for Tropical Storm Don:
It is a little bit stronger tonight and the forward speed is about as fast as it's been throughout the day. The target is still the middle Texas coast, but tonight's forecast is a little bit south of Corpus Christi. If this pans out, we might miss out on really substantial rain. Here's the official track from the National Hurricane Center:
Here's a projection of the expected rainfall through the day Friday:
As with most tropical systems, the heaviest rain may fall north and east of the center as it approaches the coast. Highest rainfall totals may be from Matagorda Bay southward toward Corpus Christi. There may still be isolated, brief tornadoes or waterspouts near the coasts of Matagorda and Brazoria counties.
Despite tonight's slight change in the forecasted track of Don, everyone on the Texas coast needs to be prepared. As systems approach the coast, they can and do behave very unpredictably. Its still a possibility that Don could briefly strengthen before landfall and even become a hurricane for a brief time. This is similar to what happened in 2003 with Claudette; a storm in the Gulf that made a landfall near where Don is expected to end up.
