Invest 91L

This one has shown up pretty quickly, as it wasn't designated until late yesterday as a potential area of interest. The environment is marginal in this region, especially with regard to SSTs near the coast. It's early for a system in this particular spot, but as you can see, 91L has a fairly robust mid and developing low level circulation while devoid of significant convection. This one could become a short lived depression or storm before crossing the Texas coastline in the next day or so. 

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Fri May 21 2021

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

2. Recent satellite imagery suggests that a low-level circulation is 
forming associated with the mid- to upper-level disturbance over the 
western Gulf of Mexico. However, shower and thunderstorm activity 
remains disorganized. Environmental conditions are expected to be 
marginally conducive for development, and a short-lived tropical 
depression or storm could form before the disturbance moves inland 
over the northwestern Gulf coast tonight. Regardless of development, 
the system could produce heavy rainfall over portions of 
southeastern Texas and southwestern Louisiana during the next few 
days.  Additional information on the rainfall and flooding potential 
can be found in products issued by your local National Weather 
Service Forecast Office. 
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

2pm outlook. Odds up to 60%.

2. Surface observations and recent satellite wind data indicate that a 
well-defined low pressure system over the western Gulf of Mexico has 
winds of 30-35 mph near and east of the center. The associated 
shower and thunderstorm activity remains limited, but any increase 
in this activity may result in the formation of a short-lived 
tropical depression or storm before the system moves inland over the 
northwestern Gulf coast tonight, and potential tropical cyclone 
advisories may be needed as early as this afternoon.  Regardless of 
development, the system could produce heavy rainfall over portions 
of southeastern Texas and southwestern Louisiana through Saturday.  
Given the complete saturation of soils with ongoing river flooding 
along the Texas and Louisiana coastal areas, heavy rain could lead 
to flash, urban, and additional riverine flooding across this 
region.  Additional information on the rainfall and flooding 
potential can be found in products issued by your local National 
Weather Service Forecast Office. 
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

Not that I am bored with TX/LA after last year, but can we get something different this year?  ;)

Of course sparing the Central West Coast of Florida another year...
