From Meteorologist Zack Fradella as of 5 p.m. central time:
Tropical Storm Harvey continues to dump feet of rain on Southeast Texas and the metropolitan Houston area, meanwhile a new system is expected to develop off the Carolinas for the start of the new week.
Harvey has produced between 20-30″ of rain in the past 24-48 hrs across a large portion of Southeast Texas where an additional two feet of rain is possible over the next few days as Harvey slowly meanders back offshore. It’s now becoming a reality that Harvey will move back off the Texas coast on Monday and could restrengthen slightly before making a second landfall near Galveston on Wednesday. As the storm sits offshore, heavy rain bands will continue to spill into Texas and Louisiana causing even more widespread flooding.
Mark is covering the flooding in Houston and placed a camera along 610 where Braeswood crosses underneath near Brays Bayou.
The National Hurricane Center states that as much as 50″ of rain are possible when all is said and done. Harvey is not expected to dissipate until it moves far enough inland which is not expected to occur until the end of this week.
Off the Carolinas is Potential Tropical Cyclone #10 which was labeled as of the 4 p.m. CT advisory from the National Hurricane Center. This system is expected to strengthen into Tropical Storm Irma on Monday but remain a weak tropical storm as it tracks right along the South Carolina and North Carolina coastal areas on Monday and Tuesday. By midweek the storm will quickly be moving out to sea where little strengthening is expected. The coastal areas of the Carolinas has the potential to receive a few inches of rain but no major impacts are expected.
