Re: EPAC: INVEST 91E
A broad area of low pressure located a couple of hundred miles
south of the Guatemala/Mexico border is producing disorganized
shower and thunderstorm activity. Environmental conditions are
forecast to be conducive for development of this system, and a
tropical cyclone is expected to form south of the southern coast of
Mexico within the next few days while the disturbance moves westward
at 10 to 15 mph.
* Formation chance through 48 hours...medium...50 percent
* Formation chance through 5 days...high...90 percent

True... Just realized that.
To touch up on the GFS's future depictions of future Sandra:
The GFS this year has either under-forecast storms or over-forecast. Some of its runs never really did materialize in terms of strength.
But for Patricia, it initially showed it *only* dropping to millibars in the 940's range. I don't think any of the medels foresaw the perfect trough interaction. So considering that Sandra will form in a relatively close area to Patricia's, it could become quite strong.

What do you mean by that? Unless you think Sandra could be a record-breaker like Patricia?
I don't know about Patricia but it could be very strong. Usually when you fly recon into this area of the Pacific they find pressures lower than estimates (i.e. Odile). Looking at some guidance it could be another tight core bomber if things go right with small wind field.

Not sure if this will be one of those storms with really low pressures. It's large, but the environmental pressures shouldn't be that low at this time of year and this is under a ridge.
