Watch out Brownsville...Claudette's 'a-comin.

The National Weather Service on Saturday was sticking to the forecast that the federal agency had maintained for several days for Tropical Storm Claudette: landfall as a tropical storm or minimal hurricane near or south of Brownsville late Monday or early Tuesday.

The expectation was that a trough of low pressure over the Mississippi Valley, which was pulling Claudette north-northwest at 8 mph on Saturday, would push east late in the day, allowing an area of high pressure to take its place. Then, the clockwise circulation of the high pressure area would steer Claudette into a sharp left turn, pushing it westward to right at or below the mouth of the Rio Grande.
