    Nice video Dr.Cowan! Thanks for keeping us up to date and not forgetting Hawaii!

  • Sean says:

    Thank you Levi, very informative and enjoyable presentation as usual.

  • Patrick Petrisky says:

    What about the cold water coming up from Brownsville over to corpus. It is 3oc colder,

    Also, as to it going more south. The low that was pulling more west southwest seems to have just stopped cold against all the dry air over California. Do you think this will slow down Hanna or cause it to rebound more north on the cone of uncertainty?

  • Patrick Petrisky says:

    And thanks for your commentary also!

    One more thing…

    Does the gfs model rely on aircraft data? It is usually pretty accurate (at least in previous years).

    Some friends and I hypothesized that lack of airline traffic due to covid could have caused a lack of data for model corrections. What do you think on that?

    Sorry to bombard you with questions, but I appreciate your comments. I like to learn.

    Love your videos Levi. I learn something new with each one. There is something I’d like to know about the wind direction of tropical systems. It seems so strange when a storm is approaching and the wind is coming out of the north, even though the storm is to the south, then it keeps changing direction. Is there an easy way to remember where in a storm you are situated depending on the wind direction? So far, in general, the best way I have figured is that wind blows toward the low pressure, but this doesn’t seem to be the case with tropical systems.

    I really appreciate Tropical Tidbits. My old go-to site stopped detailed reporting of tropical weather ( took it over) and now just has ordinary weather reports. I like to look at trends in forecasts such as how the forecast landfall moves over time. For instance Hurricane Rita in 2005 was a disaster for Houston not due to the storm, which missed Houston entirely, but the attempted evacuation due to the predicted Houston landfall. I live in Houston and unless one plans very far in advance there is no way we can evacuate simply due to the size of the population.

    #1 Go to site should always be the National Weather Service.
    The NWS locally is who has the best information.

    They update things a lot more than this site as well.

    If you have Twitter follow the NWS out of Houston.

  • Jake says:

    I don’t think you can live in Houston without paying attention to them because of the constant flood risk.

  • Graham Knopp says:

    Thank you Jake for talking about Douglas. The reality is here in Hawaii that we are very vulnerable to the effects of tropical storms. Small changes in the path of Douglas will results in huge changes to the effects. While there is a widespread belief that the mountains of the Big Island protect us, Honolulu has not really been tested by such a storm in the historical period – both Iwa and Iniki were near-misses to the Island of Oahu. I look forward to your upcoming posts.

  • Stacey Boudreaux says:

    Seems like a whole lot of frequencies dancing thru the clouds above land. what gives?

  • Mariana Monte Alegre Schwarz says:

    Thanks Levi, we’re at Grenada, first time in a hurricane season and I’ve been following your videos. Than you so much for your work, it’s brilliant! Best source to really understand the models and the forces of nature. Thanks a lot!
