Atmospheric rivers form when large, concentrated bands of moisture-laden air flow toward higher latitudes, often along a jet stream. They develop due to specific wind patterns that transport and focus warm, moist air over long distances, leading to heavy precipitation when the moisture is forced upward by mountains or fronts.
We will continue to monitor trends as the models can change day to day. As I mentioned in the video, until this system gets on shore on Sunday in the Pacific NW, we only have what we "think" the system will do based on atmospheric conditions that we think will be present at that time. This is due to the fact there are not a lot of land masses in the Pacific Ocean as well as observation sites to gather data from. So a lot of dependencies for sure! Once the system moves on shore, we will get actual data elements and the models will be able to react to those a lot quicker.
Hi there! Thanks for checking in. Here at The Weather Farm, we’re committed to a regular schedule: every Monday morning, we share an outlook for the upcoming week, and on Friday mornings, we highlight the major weather stories for the weekend and early next week. When big weather events are in play, we add a Wednesday morning video to keep you up-to-date with the latest model runs and developments. Plus, we're planning to go live during significant storms, so stay tuned! If you're looking for local Indiana weather updates, check out TWF Local, which we post on our Facebook page. Thanks for being part of The Weather Farm community!
Great question - a couple of factors are at play here - we have seen incredibly warm Sea Surface Temperatures (SSTs) for the last two hurricane seasons. We also were in an El Nino pattern and are currently in an ENSO neutral pattern bordering on a weak La Nina pattern. Typically El Nino patterns produce lower than normal number of hurricanes in the Atlantic Basin but when storms do develop, they tend to benefit from the relatively "untouched" warm waters that can rapidly intensify storms.These two factors have contributed to stronger storm systems that are both more frequent and severe than in an average season.

Do you think this weather will impact any Thanksgiving travel?

it seems that we have been a series of potential storms in the tropics. Is thist normal, or just due to unusually warm sea temperatures?
