2013 Atlantic Hurricane Season Birdseye Discussion #85A (Special Update)

...FRIDAY SEPTEMBER 6 2013 6:25 PM EDT...
Tropical disturbance Invest 99-L in the southwestern Gulf of Mexico...mentioned in paragraph P7 of discussion #85...became tropical depression eight early this afternoon while making landfall in east-central Mexico. Primary threat from this system will be potential for flash floods and or mudslides as it moves inland into central Mexico tonight. Due to landfall...I suspect this system will have dissipated as a tropical cyclone by the release time of my next discussion and therefore will be unable to release a track or intensity forecast on this system.

I am no longer considering tropical wave Invest 98-L southwest of the Cape Verde Islands as a special feature as the system appears to have weakened thunderstorm activity while ingesting Saharan dry air mentioned in paragraph P5 of discussion #85. In addition...the tropical wave is about to encounter unfavorable upper winds associated with mid-ocean upper vortex mentioned in the Invest 98-L section of discussion #85.

No updates on any other systems in the Atlantic tropics. Return to full discussion #85 for an assessment on the rest of the Atlantic tropics.
