A small low pressure system located a little more than 1000 miles east of the Lesser Antilles continues to produce disorganized showers and thunderstorms. This system has changed little in organization since yesterday, but conditions are still expected to be conducive for the formation of a tropical depression during the next day or so while the system moves slowly northwestward to west-northwestward. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. Shower activity associated with a broad area of low pressure over the northwestern Gulf of Mexico has become a little more concentrated during the past several hours. Nearby observations indicate that although pressures are falling in the area, there are no signs of a surface circulation at this time. Some slight development is possible before the system moves inland along the northwestern Gulf coast Tuesday night. Regardless of development, this system is expected to produce locally heavy rainfall and possible flash flooding along portions of the central and upper Texas coastal areas later this week.
