Close in Development?

While NHC remains fixated on a slight chance (10%) for development far off the U.S. East Coast, I'm seeing what appears to be a weak rotation trying to develop just east of the mouth of the River.  Boothville has received 4-5" since midnight as T-Storms are taking up a banding type appearance.  Surface pressures are not falling so this could be a weak low in the mid levels (above 5,000') ?  Whatever, it is enhancing the potential for heavy rainfall over SE LA/MS for the rest of this afternoon and into Tuesday.  Some spots could easily pick up 2-4"+ during several hours that could cause some street flooding.   Stay alert as we all know the difficulty the Sewer & Water Board has encountered keeping our streets clear of rainwater,  Down the road, a tropical wave in the Western Caribbean could bring another surge of tropical moisture to us later this week.   For now, let's focus on this old frontal boundary along the northern Gulf & keep a watch for possible development that could bring more tropical downpours.   I'll post late this PM or this evening.  Stay tuned!
