TROPICAL DEPRESSION BILL DISCUSSION NUMBER   6
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL022015
400 AM CDT WED JUN 17 2015

While radar data show that Bill is maintaining a good
convective banding structure, surface observations indicate that
the cyclone has weakened to a tropical depression over central
Texas.  The initial intensity is 30 kt, with these winds occurring
in rainbands near and east of the center.  The large-scale models
suggest that only slow weakening will occur during the next 24-36
hours, and Bill is likely to remain a tropical cyclone until the
center moves into eastern Oklahoma on Thursday.  After that, the
cyclone is expected to degenerate to a remnant low, with the low
being absorbed by a frontal system over the eastern United States
in about 96 hours.

The initial motion is 360/11.  Bill is expected to moved northward
for the next 12-24 hours on the west side of the subtropical ridge.
Subsequently, the cyclone should turn northeastward as it enters
the westerlies.  The track model guidance is in good agreement with
this scenario, and the new forecast track lies close to the model
consensus.

The main hazard from Bill is expected to be heavy rainfall and
flooding across portions of eastern Texas and eastern Oklahoma
over the next day or two.  Please see products from your local
National Weather Service office for more information on the flood
threat.

This is the last advisory on Bill issued by the National Hurricane
Center.  Future information on this system can be found in Public
Advisories issued by the Weather Prediction Center beginning at 10
AM CDT, under AWIPS header TCPAT2, WMO header WTNT32 KWNH, and on
the web at http://www.hpc.ncep.noaa.gov/tropical/.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 400 AM CDT (0900 UTC), the center of Tropical Depression Bill was

depression is moving toward the north near 13 mph (20 km/h).  This
general motion is expected to continue today with a turn to the
northeast on Thursday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Slow weakening is forecast during the next 48 hours, and the
depression is expected to become a post-tropical low on Thursday.

The estimated minimum central pressure is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND

RAINFALL:  Bill is expected to produce total rain accumulations of
4 to 8 inches over eastern Texas and eastern Oklahoma and 3 to 6
inches over western Arkansas and southern Missouri. Isolated
maximum amounts of 12 inches are possible in Texas and Oklahoma.
These rains may produce life-threatening flash floods.

WIND:  Wind gusts to tropical storm force are occurring in
rainbands to the east of the center.  These gusts should subside
today.

STORM SURGE:  Above normal tides along the Upper Texas and Western
Louisiana coasts should subside today.

TORNADOES:  A brief tornado or two may occur over parts of eastern
Texas and eastern Oklahoma today and tonight.
