The 1800Z cycle of the HWRF2 model  for an Invest system (AL90) in the 
eastern Atlantic had to be cancelled due to model instability and  the 
start of the  00Z cycle.   (As a side note the GFDL model for this 
invest system ran and completed successfully).  The course of action 
being taken which has been discussed by by developers and the SPA staff 
is as follows;   If the 00Z HWRF2 fails and it is due to model 
instability we are to set it to complete.   If there is a 06Z run for 
90AL Invest and it should fail due to model instability then the 
developers have provided a work around that will be implemented.
