Danny hangs on by a nail, begins northward motion
August 28, 2009
Tropical Storm Danny has begun its northward motion based on the latest reconnaissance. Winds have dipped in many areas of the storm, however one region did record sustained winds of 40-45 mph, thus holding on to the “tropical storm” designation.
Danny may strengthen slightly as it moves under an area of moderate upper level convergence over the next 24 hours. However the system will then encounter strong shear associated with a surface front measuring around 35 knots, which will eventually convert Danny to an extra-tropical system at roughly 36 hours.
The chance of the east coast experiencing sustained tropical storm forced winds (35+ mph) is relatively low at this time.
You can see from the image below from Wunderblog just how much the storm has struggled with the shear affecting the convection. The areas of heaviest activity are well east of the central rotation, which has caused multiple reformations thus far.
