Karen's associated convection is becoming increasingly
disorganized, and as has been stated in previous advisories, the
circulation is elongated and attached to a surface trough that
extends northward toward Post-Tropical Cyclone Jerry. A partial
ASCAT pass only showed winds around 25 kt in the southern part of
the circulation, and the initial intensity is therefore lowered,
probably still generously, to 30 kt.
Karen has moved out from beneath an upper-level anticyclone and is
now feeling the effects of 15-20 kt of northwesterly shear. The
shear is expected to increase further during the next few days and
also become more southwesterly, which is likely to lead to
weakening and further loss of organization. Based on the latest
global model guidance, Karen is now forecast to lose organized deep
convection and degenerate into a remnant low in 12 hours and then
open up into a trough by day 3. Given the cyclone's current
structure, however, it's entirely possible that either of these
options could occur as soon as later today.
Lorenzo is exactly what we want out of Category 4 Hurricanes. It’s becoming extremely strong and well organized but it’s not expected to go near any major landmasses. Always nice to see a storm this powerful go and bugger off in the North Atlantic without hurting anyone.
11am NHC advisory is out on Depression #11. Good news for pretty much everyone. Even further offshore and not expected to become a hurricane anywhere near land. ECMWF called this a about 36 hours ago and now UKMET and GFS are coming into agreement with it. The Bahamas are going to get a day or so of very bad weather, but absolutely NOTHING like Dorian.
Invest95L is a tropical system that is moving through central Caribbean. Conditions are becoming favorable for a tropical depression or a tropical storm to form within the next day or so as the system moves toward the northwest through the northwestern Bahamas and toward the Florida Peninsula at 5 to 10 mph. The NHC says 70% of formation in the next 48 hours and 80% in the next 5 days. The ECMWF (EURO) Model suggests that formation is likely and that this storm will remain off the Florida coast while following a similar track to Dorian.
An introduction about what you can expect from this website
Hello and welcome to Tropics Watch! As the site’s tagline says, this is a website dedicated to “Maps, Figures, and Opinions on Atlantic Hurricanes” from the perspective of a Northeast Florida resident who’s seen a hurricane or ten. I should clarify upfront that I am not a professional meteorologist nor have I studied to be one in a formal capacity, but I am fascinated by tropical weather and the awesome (and terrible) power of tropical cyclones.
This site will include reflections on all sorts of severe weather-related topics including
Supplies, relief, and logistics for affected areas
Some hurricane mythbusting
The economic impacts of these sorts of storms
Track and Forecast updates
Output and discussion of forecasting models
The worldview implications of hurricanes
…and many others!
Since I live in Northeast Florida, I will also include forecasts and information that specifically pertains to the area where I live. Any content of this nature will be crossposted to the Northeast Florida Hurricane Updates Facebook page. Not everything on Tropics Watch will be sent to that Facebook group; only things that specifically pertain to Northeast Florida.
So thanks for stopping by! I hope that you will find the content of this site to be useful or at least interesting.
