The NOAA Gulfstream is scheduled to sample the environment over the Gulf later today and an Air Force reconnaissance aircraft is scheduled to investigate the system tomorrow. * Formation chance through 48 hours...high...90 percent. * Formation chance through 7 days...high...90 percent.

Southwestern Gulf of America (AL92): A trough of low pressure over the southwestern Gulf of America is producing disorganized showers and thunderstorms. Although environmental conditions appear only marginally conducive for development, a tropical depression is likely to form within the next couple of days. The system is expected to drift east-northeastward through the middle portion of the week before turning northward. It is too early to determine specific impacts to the northern Gulf Coast, but interests there should closely monitor the progress of this system. * Formation chance through 48 hours...high...80 percent. * Formation chance through 7 days...high...80 percent.

Southwestern Gulf of America: A trough of low pressure in the southwestern Gulf of America is producing disorganized showers and thunderstorms. Although environmental conditions appear to be marginally conducive, gradual development is becoming more likely, and a tropical depression is likely to form during the middle or latter portion of the week. This system is expected to drift eastward over the next few days, before it turns northward. * Formation chance through 48 hours...low...30 percent. * Formation chance through 7 days...high...70 percent.

Southwestern Gulf of America: A surface trough of low pressure has developed along the coast of Mexico in the southwestern Gulf of America. Although environmental conditions are expected to be only marginally conducive, gradual development of this system is possible and a tropical depression could form by the second half of this week while it initially drifts eastward before turning northward. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...medium...50 percent.

Southwestern Gulf of America: An area of low pressure is likely to form around the middle of the week over the southwestern Gulf of America. Although environmental conditions are expected to be only marginally conducive, some slow development is possible and a tropical depression could form late this week while the system drifts northward. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 7 days...medium...40 percent.

Southwestern Gulf of America: A broad area of low pressure could form in a few days over the southwestern Gulf of America. Some subsequent slow development of this system is possible while it drifts northward over the southwestern Gulf. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 7 days...low...30 percent.

Southwestern Gulf of America: A broad area of low pressure could form in a few days over the southwestern Gulf of America.

Southwestern Gulf of America: A broad area of low pressure could form in a few days over the southwestern Gulf of America. Any development of this system is expected to be slow to occur as it drifts over the southwestern Gulf waters. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 7 days...low...20 percent.

Subtropical West-Central Atlantic (Remnants of Fay): Showers and thunderstorms associated with the remnants of former Tropical Storm Fay located several hundred miles southeast of Bermuda have become less organized since yesterday. No further development is expected while it moves north-northwestward at 5 to 10 mph to the east of Bermuda. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 7 days...low...near 0 percent.

Subtropical West-Central Atlantic (Remnants of Fay): Showers and thunderstorms associated with a trough of low pressure (the remnants of former Tropical Storm Fay) located several hundred miles southeast of Bermuda have become less organized during the past several hours. Dry air and strong upper-level winds are expected to prevent significant re-development while it moves north-northwestward at 5 to 10 mph to the east of Bermuda. Any formation chances should end by Sunday due to very strong upper-level winds. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent.

Subtropical West-Central Atlantic (Remnants of Fay): A trough of low pressure associated with the remnants of former Tropical Storm Fay is located several hundred miles south-southeast of Bermuda. Despite ongoing thunderstorm activity, dry air and strong upper-level winds are expected to prevent significant re-development while it moves north-northwestward at 5 to 10 mph to the east of Bermuda. Any formation chances should end by Sunday due to very strong upper-level winds. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent.

Subtropical Central Atlantic (Remnants of Fay): An area of low pressure associated with the remnants of former Tropical Storm Fay is located several hundred miles southeast of Bermuda. Despite ongoing thunderstorm activity, dry air and strong upper-level winds are expected to prevent significant re-development while it moves northwestward, to the east of Bermuda. Any formation chances should end by Sunday due to very strong upper-level winds. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent.

Subtropical Central Atlantic (Remnants of Fay): A low pressure area associated with the remnants of former Tropical Storm Fay is located several hundred miles southeast of Bermuda.
