Western Gulf:
A broad area of low pressure has formed over the far southern Bay
of Campeche and is producing disorganized showers and thunderstorms. Environmental conditions are forecast to be only marginally
conducive for development before the system moves inland over
eastern Mexico late Saturday or Sunday. The system could re-emerge
over the northwestern Gulf on Tuesday and Wednesday while
interacting with a frontal boundary, but there too, conditions are
only expected to be marginally conducive for any development.

For the North Atlantic...Caribbean Sea and the Gulf of America:

Southwestern Gulf:
A broad area of low pressure just offshore of eastern Mexico
continues to produce some shower and thunderstorm activity. While
this system has become better organized since yesterday, marginal
environmental conditions will probably prevent significant
development before the low moves inland over eastern Mexico by
Sunday. The system could re-emerge over the northwestern Gulf on
Tuesday or Wednesday while interacting with a frontal boundary, but
conditions there are also expected to be only marginally conducive
for development.

For the North Atlantic...Caribbean Sea and the Gulf of America:

Northwestern Gulf of America:
A trough of low pressure located over northeastern Mexico continues
to produce disorganized shower and thunderstorm activity.
Development is not expected during the next day or so while the
trough remains inland and drifts generally northward over
northeastern Mexico and southern Texas. The system is then forecast
to move northeastward and could re-emerge over the northwestern Gulf
of America late Tuesday or Wednesday, where environmental conditions
may support some development around midweek.

Regardless of tropical cyclone formation, heavy rainfall, flash
flooding and gusty winds are possible across portions of eastern and
southern Texas and Louisiana this week. Additional information on
this system can be found in products issued by your local National
Weather Service Forecast Office.

For the North Atlantic...Caribbean Sea and the Gulf of America:

Northwestern Gulf of America (AL90):
A broad area of low pressure located inland over south Texas is
producing a large area of disorganized showers and thunderstorms.
The system is forecast to move northeastward along the Texas coast
and could emerge over the northwestern Gulf of America later
today or tonight. Environmental conditions are expected to be
marginally conducive for the formation of a short-lived tropical
storm late today or on Wednesday, especially if the system moves far
enough offshore.

Regardless of tropical cyclone formation, interests across southern
and eastern Texas and portions of Louisiana and Mississippi should
prepare for periods of intense rainfall over the next several days
which could produce widespread, life-threatening flash, urban, and
river flooding. Gusty winds and coastal flooding are also possible
along portions of the northwestern Gulf Coast, and Tropical Storm
Watches or Warnings could be required later today. Additional
information on this system can be found in products issued by your
local National Weather Service Forecast Office or NHC Key Messages.
