Tropical Storm Isaac Moving Toward the the Northern Gulf Coast

Will Isaac impact the southeast states?

I thought I'd start a new post on what is currently Tropical Storm Isaac. The latest 5pm data shows the following:


SUMMARY OF 500 PM AST...2100 UTC...

INFORMATION----------------------------------------------
LOCATION...16.0N 61.2W
ABOUT 25 MI...40 KM SSE OF GUADELOUPE
ABOUT 365 MI...585 KM ESE OF SAN JUAN PUERTO RICO
MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H
PRESENT MOVEMENT...W OR 280 DEGREES AT 22 MPH...35 KM/H
MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES


While there is a large amount of uncertainty in Isaac's path, especially this far out, Isaac is something that everyone in the southeast needs to be watching closely. Right now the computer models show Isaac moving toward the Gulf of Mexico in about 96 hours. Depending on the exact path that Isaac follows, it may already be a hurricane by the time it gets there. People in Florida and all along the Gulf Coast area need to pay special attention as Isaac gets closer.

 
Today Isaac has had a difficult time gaining strength due to dry air being drawn in to the system at mid levels of the atmosphere. Some believe that this advection of dry air will end by morning if it hasn't already. Either way, Isaac is forecast to be a hurricane within 48 hours, taking a path almost directly over Jamaica. If it stays to the south of the big islands, and the mountains on Haiti in particular, Isaac could gain strength over the very warm Caribbean waters, which are 86 to 89 degrees.

 
I have a web page just for Isaac that has everything you might need to know about Isaac with the most up to date information possible. On that page are links to other tropical weather information pages for the entire tropical Atlantic basin. Take a few minutes to explore all of the tropical maps, charts, discussions, and the latest satellite images. 

While Isaac won't affect us (if at all) until Monday, there is a very real possibility that Isaac could follow a path that may potentially bring us the tropical moisture that we need to break the drought. 

I'll be making periodic updates as Isaac progresses, please check back for more information.

The leading edge of the first tropical clouds is just now entering the metro area. There are showers passing Macon and moving northwest. Take a look at this beautiful image: http://www.daculaweather.com/4_sat_se_us_gulf_z.php

The next NHC update on Isaac will be at 8am. It appears that Isaac is finally forming an eyewall this morning ( http://www.daculaweather.com/4_gmex_ft_loop.php ) and beginning to gain a little strength. I believe that the next advisory will be an upgrade to Hurricane Isaac. Isaac will be a minimal hurricane when it reaches shore later today with winds of 80 mph or so. The main threat will be storm surge and extremely heavy rains. More in just a little while... New image uploaded also.

700 AM CDT TUE AUG 28 2012 - INTERMEDIATE UPDATE ...RECONNAISSANCE AIRCRAFT FIND ISAAC NEARLY A HURRICANE... SIGNIFICANT STORM SURGE AND FRESHWATER FLOOD THREAT TO THE NORTHERN GULF COAST... SUMMARY OF 700 AM CDT...1200 UTC...INFORMATION ---------------------------------------------- LOCATION...27.8N 88.2W ABOUT 105 MI...170 KM SSE OF THE MOUTH OF THE MISSISSIPPI RIVER ABOUT 185 MI...295 KM SSE OF BILOXI MISSISSIPPI MAXIMUM SUSTAINED WINDS...70 MPH...110 KM/H PRESENT MOVEMENT...NW OR 305 DEGREES AT 7 MPH...11 KM/H MINIMUM CENTRAL PRESSURE...976 MB...28.82 INCHES -------------------------------------------------- Isaac should become a hurricane before the 10am update. As soon as it does, I will create a new blog post and update you. Isaac has slowed down from 12 mph to 7mph. This decrease in forward speed could be devastating for the Louisiana coast and for inland flooding. More updates in a while.

Multiple clean 60-63 kt SFMR datapoints with a Flight Level wind of 80 kt and peak 10s Flight Level wind of 86 knots. I think we can safely call Isaac a hurricane.
