Re: Forecast Coastal Low in Gulf Next Week

The two basins that bookend the continental United States have yet again found some equilibrium this year, as Invest 94E in the extreme eastern Pacific has become Tropical Storm Norman, making for an "N" storm occurring at the same time in both the East Pac & Atlantic.

Norman is forecast to strengthen a little before pushing inland on the eastern side of the Gulf of California as a modest tropical storm. From there we are likely to see some separation taking place, with some of the more mid to upper level moisture and vorticity heading east to northeast, potentially increasing the odds of cyclone development in the western Gulf of Mexico as mentioned in the first entry, with the lower level vorticity stuck trapped in the Gulf of California, or slowly crossing inland Mexico.

In the visible satellite image below you can see Norman centered just off the southernmost tip of the Baja, as well as the remains of former Hurricane Miriam to its southwest. All that is left of Miriam now is a low level swirl. And yet another swirl, this a transient low to mid level feature, is noted to the north-northwest of x-Miriam. An interesting mix!
