Hurricane Ida has entered an extended “landphoon phase” where it feeds off the latent and sensible heat of the Louisiana Bayou swamps. It will trudge northward dumping untold amounts of rain. pic.twitter.com/kae4RDwVcm

This composite imagery is called a “sandwich” loop, and it is made by combining visible and infrared satellite imagery channels. The resulting multi-dimensional image gives meteorologists and researchers additional insight into severe weather, such as #Hurricane #Ida, below. pic.twitter.com/ojOE5xaKKe

Ida still expected to move onto the Louisiana coast tomorrow as a very dangerous, major hurricane. The main wind and storm surge issues will be along and east of the center of circulation; keep in mind wind, and rainfall impacts will extend far from the center. pic.twitter.com/pHruhxuUdt

Due to the expected size and power of Hurricane Ida, Gulf of Mexico waters will rise well in advance of the storm’s arrival near the coast, which is expected later Sunday or Sunday night. Forecasters caution that bay, lake, and bayou water levels will increase as well. pic.twitter.com/5xhzMUtPjE
