Isaac is now a Tropical Storm and will most likely intensify into a Hurricane. Here is a Forecast model:
As can be seen, it is expected to ride along side the West Coast of Florida as a Hurricane. I have family in Naples, FL. They are prepared for Isaac when it arrives before 2 PM Monday afternoon. They will feel the effects for a while before and after 2 PM. I live in Tampa, FL and will be the next to feel the effects of Isaac. On that note I am also prepared.
I’ve been checking the models on http://www.twisterdata.com for when Isaac makes landfall and where it will be on the 28th of August. Now to explain the models I am going to show you. These models show Isotachs or lines of equal windspeed at upper levels of the atmosphere. The shaded parts are the wind speed in knts (1 knt = 1.15078 mph). The RAP models are for next 18 hours, so they won’t be useful as of right now. The NAM and the GFS models will be used. However the NAM is only up the the next 4 days, until the 26th, but anyway here is one model from the 26th:
The GFS models are the most useful for right now with a prediction period of up to 17 days, there are bound to be inconsistencies. Anyway the GFS models show Isaac shooting across Cuba and re-emerging on the Straight of Florida:
As one can see already, the GFS models put the track of Isaac more West then the NAM models. Continuing on, Isaac is now off the beaches of Marco Island and Naples.
This is Isaac at 06 UTC or 2 AM EST (I think):
Isaac makes landfall on the 28th at 18 UTC or 2 PM EST (I think):
As Isaac passes just West of Tampa, FL, the Relative Humidity will be 95%:
There will be a lot of Moisture in the air. This means lots of rain. Just to show how much rain is possible:
But that is not the whole scale of Precipitable Water…
… 3 or more inches.
And now for Radar Images~
This is one of my favorite radar techniques Near InfraRed, it is also looped (updated every 30 minutes)
