The Weather Channel announced at 11:00 a.m. on August 28 that the National Hurricane Center is keeping Isaac at tropical storm status. Hurricane expert Jim Cantore noticed a pressure drop and reported at 10:15 on Twitter, “Newest recon shows pressure drop to 977mb and 89kts outbound wind in northeast quadrant. NHC could upgrade b4 next advisory.” However, Cantore posted earlier that there isn’t much difference between a tropical storm and a weak CAT 1 storm. “It’s like a promotion at work with no pay.”
The latest advisory from the National Hurricane Center, as reported at 11:00 a.m. ET on Tuesday, August 28, shows that Tropical Storm Isaac is very close to a hurricane, but remains a tropical storm. Isaac is located at 28.1 N/88.5 W. Its maximum winds are 70 mph and its pressure dropped to 976 mb. The storm is currently traveling NW at a speed of 10 mph. Isaac is located 77 miles SSE of the mouth of the Mississippi and 161 miles SE of New Orleans.
Despite remaining a tropical storm, Isaac still poses a threat. “This is going to be one of the more serious storms move into New Orleans in a while,” one Weather Channel reporter said at 10:50 a.m. However, he also noted that New Orleans is better protected by reinforced levees. The problems will include localized flooding and power outages caused by sustained rain and tropical storm force winds.
Bryan Norcross said that people might sit up and take notice more if Isaac is upgraded to a hurricane. “From a PR standpoint, it might be better to call it a hurricane. Yes, it’s right on the cusp, but it’s not quite there.” He added that hurricane hunters take hundreds of measurements to ensure accuracy.
