With things starting to heat up in the Tropics it looks like we will get to feel the effect of some of that weather, even if it is just rain.

Harvey is expected to come in to the US as the first landfalling hurricane this year. With the lack of a steering current in the upper atmosphere it could dump tons and tons of rain over the areas it travels.

I certainly hope New Orleans gets their pump problems solved prior to early next week. If Harvey drifts over the SE at a slow pace it could be devastating in the way of flooding for many locations.

The GFS and CFS are on two totally different solutions for the path and timing. The NAM only reaches out to 84 hours or so, so it doesn't have an opinion yet.

If the GFS proves out, we could see Tuesday or Wednesday highs in the 60's with a lot of rain.

Here's the NAM map showing a double whammy for the US, one landfall storm and one just brushing the SE / Atlantic coastline.

Note the "M" on the landfall potential chart. That is for "Major" hurricane. This is a dire situation. The Governor of Texas has already declared 16 counties Disaster Areas ahead of this landfall.

I can't tell if they're running bets on this storm in Vegas or are being intellectually honest with this banter.

Harvey is exploding into power. He looks to be a serious threat to life and property along the Texas coast.

The Mets are starting to get real nervous about Irma. This seems to be a year like 2005 when there were a slew of named storms and even a good handful of Cat 5's.

Irma

We are a week out so there is still much uncertainty in where this storm is going. However, now only a week out there is more guidance on where it might go.

Here is the Euro prognostication for the 240 hr. model run.
The GFS doesn't put Irma even close to land until the 300 hr model and even then recurves it back out to sea.

Nate

After a days worth of modeling Nate seems to the locked in to a SE LA landfall as an estimated Cat 1 storm that will rapidly move off to the NE.

The spread of the moisture to the East of Nate is unknown right now. but hopefully us Jawja folk will get a little out of it.
