ALT A broad area of low pressure is forecast to form over the southwestern Gulf of Mexico in a day or two. Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form by the middle part of next week while the system moves slowly westward or west-northwestward. Regardless of development, several days of heavy rainfall are expected across portions of southern Mexico and Central America. These rains are likely to cause life-threatening flooding and flash flooding. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 7 days...medium...60 percent.
