10:00 AM Friday Update from Jeff:
Hurricane Harvey approaching the middle TX coast.
Rain bands and winds increasingconditions will be rapidly deteriorating today.
All preparations should be completed at this time.
Tropical Storm force wind gusts and storm surge moving into the middle TX coast.
Discussion:
USAF mission and coastal radars show the formation of a complex inner core dynamic situation within Harvey with double wind maximum in place. One maximum is found at 12 NM from the center (inner eyewall) and the second is at 28 NM (second eyewall). The pressure has fallen to 949mb or down from 958mb this morning, yet surface winds have not responded to the lowered pressure likely due to the fact that Harvey is in an eyewall replacement cycle. Current sustained winds are near 110mph. It appears from the radar data out of BRO and CRP that Harvey is in no hurry to complete the eyewall cycle so expect the intensification to level off over the next few hours. With that said winds could increase some as the wind/pressure relationship attempts to equalize
There has been no significant changes to the forecast track nor intensity up through landfall.
Rainbands have begun to move inland along the entire TX coast which is a little faster than expected, especially along the upper TX coast.
The threat for tornadoes will be increasing and a Tornado Watch will likely be issued shortly for the upper TX coast. The risk for tornadoes within the feeder bands will last over the next 24-36 hours and these will be fast moving with little warning time.
There has been no changes to the forecast impacts to winds, storm surge, and rainfall. |
