As Weather Underground's blog explains:
Danny has started to move into an environment with more wind shear, or change in wind speed with height either in speed and/or direction, and this has caused the hurricane to be downgraded from Category 3 to Category 2 intensity . . . . Small circulations such as Danny are prone to sudden changes in intensity, which can be difficult to forecast.
Wind shear vs Hurricane Danny as it approaches the EC
Danny will encounter an ample reservoir of dry air extending westward into the Caribbean Sea.
Dry air hampers tropical cyclones by encouraging the development of stronger thunderstorm downdrafts, which then either squelch nearby thunderstorms from forming or push them away.
This dry air is also stable, meaning it suppresses upward vertical columns of air needed to maintain or form new thunderstorms.In short, we would be well-advised to follow developments and to bear in mind the particular unpredictability of small tropical cyclones.
Wind shear can blow convection away from the center from a tropical cyclone. If strong enough, it can rip apart existing tropical cyclones.
However, before closing, I want to note that Daniel is a very significant name: God is [my] judge.
And Jesus once warned leaders of Israel that while they were good at judging the signs of the skies, they were failing to properly judge the spiritual signs of their times.
DV, I will follow up on that side in a little while, a hurricane named Daniel is speaking to us, even as we all have a strange blend of hope and concern as it approaches: hope for rain to relieve a terrible drought that is seeing coconut trees dry up and die here, something I have never seen before. Concern, as hurricane winds can be astonishingly destructive.
We have not only signs in our skies but signs of our times to address.
Let us pray for showers of blessing with not too much wind. END
