Shear Weakens Karen

Southwesterly upper level winds in the words of the National Hurricane Center (NHC) had "decapitated" Karen Friday evening. The upper winds have been pushing deep convection more than 150 miles east of the center of circulation as of 10pm Friday.

As a result, Karen's winds were downgraded to 45 mph. Although gusty winds continue with this system, calling Karen a "tropical storm" at this time, is almost rather generous.

After stalling briefly, Karen was resuming a slow north-northwestward track at 7 mph. The NHC keeps Karen a tropical storm through landfall over extreme eastern Plaquemines Parish Saturday night with a second landfall late Sunday over the Florida Panhandle.

If convection does not redevelop near the center of circulation Saturday the NHC would likely downgrade Karen further to possibly a depression.

However, as long as the a well defined swirl remains in the warm Gulf waters, there will be an opportunity for redevelopment.

No major impacts from this system are anticipated for Acadiana other than the risk of tropical showers and a few storms through early Sunday morning until a strong cool front sweeps through the area.

Stay with and social media for further updates throughout this weekend for any changes, just in case.
