..TROPICAL WEATHER OUTLOOK AUG 4, 2023..

 


The tropics remains quiet for now but they will begin to get active by mid to late August.  I will continue to monitor as that persistent Azores high and Bermuda high are anchored in place to steer storms toward the east coast.  I hope that they do not stay in place but for now its looking that way.  we need to be storm ready this season Aug through October.

Stay tuned to NATIONAL HURRICANE CENTER for the latest updates!

Best regards

Sorry for the inconvenience!

A strong tropical wave in the central Atlantic has a low 20% formation chance within 48 hours and a Med 60% formation chance within 7 days.  Development of this system would be more likely northeast of the Leeward Islands.  Most of the models recurve this storm system northwest then northeast and out over the north Atlantic Ocean.

Another Wave located over the Lesser Antilles has some showers and storms but no formation.

800 AM EDT Fri Jul 28 2023

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

1. Central Tropical Atlantic:
Shower and thunderstorm activity associated with a tropical wave 
located about midway between the Cabo Verde Islands and the Lesser 
Antilles has increased since yesterday.  Environmental conditions 
are expected to be favorable for additional gradual development of 
this system during the next few days, and a tropical depression 
could form early next week while the system moves generally 
west-northwestward over the tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.

2. Southwestern Atlantic:
Disorganized showers and thunderstorms over the far western Atlantic 
near the coasts of Georgia and northeastern Florida are associated 
with a weak area of low pressure that has formed just east of 
Jacksonville.  This system is moving north-northwestward and is 
forecast to move inland over northeastern Florida and eastern 
Georgia today, and additional development is not expected.  
Regardless of development, locally heavy rainfall is possible over 
northeastern Florida, eastern Georgia, and portions of eastern South 
Carolina during the next day or so. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.  

3. Southwestern Caribbean Sea:
A large area of disorganized showers and thunderstorms over the 
southwestern Caribbean Sea is associated with a tropical wave and 
broad area of low pressure.  This system is forecast to move 
westward over Central America later today or tonight, and 
significant development is not anticipated.  Regardless of 
development, locally heavy rainfall is possible over portions of 
Nicaragua and Honduras during the next day or so. 
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

A strong wave approaching Central American has a low pressure disturbance ahead of the waves axis that is producing strong showers and storm with gusty winds.  This is a potential for flash flooding and deadly mudslides to occur.  Due to the proximity to land formation chance are Low 0%.



A trough of low pressure over Northern Florida is still enhancing storms over Florida today as it tracks north-northeastward.  A Flood Watch is in effect today as some of these training storms could produce localized flooding in those areas with weak drainage system.

..TROPICAL WEATHER OUTLOOK JULY 27, 2023..


 A tropical wave between  30-35 degree west latitude is still being monitored for development.  This wave is moving through dry air and marginal upper level conditions.  This wave has a better chance for development as it passes to the northeast of the northern Leeward Islands. 

NHC is giving this wave a Low 0% formation chance within the next 48 hours and a med 40% formation chance within 7 days.



The surface trough off the Florida east coast is stuck between two upper level lows, one in the Gulf and the 2nd east of the Bahamas.  This trough has been producing strong storms over Marsh Harbor and the Abacco Island.  

As this trough tracks slowly over the Southeast Florida coast we could see some showers and storms later this afternoon.

..TROPICAL WEATHER OUTLOOK JULY 26, 2023..

 


The National Hurricane center is monitoring a tropical wave west of the Cabo Verde Island between 25-30 degrees west latitude.  This wave has a Low 0% chance for formation within 48 hours and low 30% chance for formation 7 days.  

GFS hits that this system will develop and turn northwest around the outer ridge of the Azores high missing the eastern sea board.  This is to far out in the future to say that this is what will happen.  We continue to watch and wait.

The Euro Model doesn't seem to have any interest in this wave it does not hint at development.  Will see if it gets onboard with GFS in the coming days.




Sea Surface temps are warn enough for development.

A surface trough over Bahamas is interacting with an upper low South of Western Cuba and another upper level low east of the Bahamas. The counter clockwise rotation from the Southern Cuba upper low is producing enough upper level lift over the Bahamas to enhance showers and storms.  Some of the storms moved inland over Southeast Florida and the Florida straights this morning producing heavy, heavy rains, gusty winds and lightning.  This surface trough will proceed westward through Friday bringing more rains and storms.  Heavy rains, gusty winds and lightning will be possible over Southern Florida the next few days.  This could cause flooding in flood prone areas.
