SHIPS in love with this thing. WOW check this out from today's 18Z analysis:

Prob of RI for 25 kt RI threshold= 89% is 7.6 times the sample mean(11.7%)
Prob of RI for 30 kt RI threshold= 59% is 7.5 times the sample mean( 7.9%)
Prob of RI for 35 kt RI threshold= 33% is 5.8 times the sample mean( 5.4%)
Prob of RI for 40 kt RI threshold= 33% is 10.3 times the sample mean( 3.9%)

LGEM really cranks it up too in 4-5 day range:

Very interesting to note that the GEM/CMC model made a coup as it was the first model to develop Alvin on May 5th 12z run. GFS came in as the second model.

This is the first run by GEM/CMC on May 5th.
