LovingGulfLows Posted October 4, 2015 Share Posted October 4, 2015 What an incredible event. The water hose isn't stopping. I've always wondered what rain or even snow totals would look like when a linear band of deep, heavy precipitation stayed on top of an area and flowed in the same linear direction as the orientation of the band. Most of the time, large bands of moisture are N/S oriented and moves West so you don't stay in it very long, however this band is oriented at a WNW/ESE direction with the moisture feed moving at a WNW direction and staying over the same areas. Now I've seen to have gotten my answer. I hope people in SC/NC stay safe tonight. Just a unique and historic storm. Mother Nature always seems to find a way to give drought stricken areas a way out, in an extreme way(GA in 2009, TX//OK this year, and now NC/SC now).

ncforecaster89 Posted October 4, 2015 Share Posted October 4, 2015 Hi everyone! I am traveling tomorrow afternoon from Wilmington, NC south on hwy 17 to Hilton Head, SC. That said, I was wondering where would likely be the best place to go in the Charleston area to document the worst flooding? I ask because I'm totally unfamiliar with that area. Thanks in advance! Edit: In other words, which areas are typically more prone to flooding? Link to comment Share on other sites More sharing options...

ncforecaster89 Posted October 4, 2015 Share Posted October 4, 2015 I apologize for the snarky post. I'm just concerned about what's going on down there and your post had an ambulance chaser vibe when I read it. Perhaps I should have assumed more good faith on your part. I completely understand that logic and greatly appreciate this genuinely thoughtful post! For full disclosure, I have been doing free-lance photo journalism for various news sources dating back to Katrina in 2005. In each event, I make it a priority to spend a minimum of 6 hours (1/2 day) volunteering to help in the aftermath...after spending the first half of the day documenting it. In my humble opinion, it's the very least I can do (out of empathy and respect) for those unfortunate persons whose devastating losses I'm typically documenting. Ironically, this devastating event is occurring along the route I'm traveling in order to get to Hilton Head, SC, for the one year wedding anniversary of my wife and I. All that being said, thanks again for your conciliatory post and your genuine concern for those in harms way! Link to comment Share on other sites More sharing options...
ncforecaster89 Posted October 4, 2015 Share Posted October 4, 2015 This event reminds me alot of the historic rainfall event Wilmington, NC experienced in late September of 2010. http://www.weather.gov/ilm/2010-Sep-27to30-heavyrain That said, this event appears to be far worse in regards to damage in the worst hit areas. Edit: I pray that there is no loss of life from this event. All the reports of swift water rescues are most disconcerting! Link to comment Share on other sites More sharing options...

I have already looked up the topography of the area, but it's always better to ask the locals who have experienced previous flooding events. Hence, the purpose for my question. Turn on the weather channel. Go read their local news. Most of the roads are closed.
