Tropical Depression Karl Discussion Number  15
NWS National Hurricane Center Miami FL       AL142022
1000 PM CDT Fri Oct 14 2022
 
Karl has not redeveloped any deep convection since the last burst 
faded earlier this afternoon.  Data from an Air Force Reserve 
Hurricane Hunter flight found surface wind speeds of 20-24 kt and a 
peak flight-level wind of only 28 kt.  Therefore, the initial 
intensity has been lowered to a possibly generous 30 kt, and Karl 
is now a tropical depression.  All global models agree the cyclone 
will continue to weaken for the next 12-24 hours in the presence of 
moderate deep-layer shear and relatively low mid-layer humidities.  
The official intensity forecast now shows Karl becoming a 
post-tropical remnant low within 12 h.  

The depression is drifting southward at about 3 kt.  Model guidance 
suggests the shallow vortex will drift southwestward in the flow 
around a low-level ridge to the north for the next day or so.  The 
NHC forecast shows Karl moving inland between 12-24 h and 
dissipating inland by 36 h.
 
 
Key Messages:
 
1. Heavy rainfall associated with Karl could produce flash flooding,
with mudslides in areas of higher terrain, across portions of
Veracruz, Tabasco, Chiapas and Oaxaca states in Mexico.
