TROPICAL DEPRESSION BILL DISCUSSION NUMBER 16
WIKI-HURRICANES FORECAST CENTER
0400AM CDT FRI JUN 19 2015
Radar and satellite representation of Bill are not flattering, the system continues to be very ragged, as would be expected for a tropical system over land. Surface observations maintain that Bill has a closed, although weak, center of circulation. Wind observations support a system with winds of only around 10 to 15 knots. As winds remain weak, most of the impacts associated with Bill will continue to be flooding. Models remain in agreement that the storm will continue moving east-northeast, gradually accelerating as Bill transitions into a remnant low within about 12 to 24 hours and is absorbed by a mid-latitude cyclone in two days or shortly thereafter.
