NRL declares invests when the NHC, CPHC, or JTWC ask them to.

Two Invests before June, hopefully this isn't a sign of things to come.

From 2:05 TWD, they are calling it a "gale low"

ATLANTIC OCEAN...
A COLD FRONT IS OVER THE W ATLANTIC AND EXTENDS S TO S FLORIDA
ALONG 32N76W 28N80W. SCATTERED SHOWERS ARE WITHIN 45 NM OF THE
FRONT. A 1009 MB GALE LOW IS FURTHER E NEAR 32N72W. A SURFACE
TROUGH EXTENDS S FROM THIS LOW TO CENTRAL CUBA NEAR 22N78W. A
LARGE AREA OF SCATTERED MODERATE CONVECTION IS E OF THE TROUGH
AXIS FROM 23N-33N BETWEEN 67W-71W.

This appears to be a cold-core low forming along a cold front and moving over progressively cooler water. Perhaps they're just practicing with these invests? Not much chance of it being anything other than a cold-core nor'easter with a deep upper low aloft.

And both of them have been fish, so hopefully that is a sign of where storms will go later on.

There has been too much shear in the Caribbean for anything to get going south of the big islands.

When does the ITCZ usually shift north, relaxing the shear? The SST's are plenty warm enough for tropical development.

The NRL has been doing this to a lot of "systems" that shouldn't be invests at all. Many of them look terrible and have very little chance.

And both of them have been fish, so hopefully that is a sign of where storms will go later on.

And both of them have formed near landmass, this might be a sign of where the storms will be forming this year. :wink:

We won't have the cold fronts in July and Aug to kick these out to be fish....hold on to your seats. A BUMPPY ride is about to begin.

No surprise at all that NRL navy site doesn't have 91L anymore.

They never ran any models on this system either. I think they were just looking for more ship reports in that area.
