Automated Water Supply Model (AWSM) was developed at the USDA Agricultural Research Service. AWSM was designed to streamline the workflow used to forecast the water supply of multiple water basins.
This is a SMRF issue and I can confirm that it happens because SMRF was never setup to run the WRF method in threaded mode. It is probably possible but never tested or implemented.
Cannot run code with WRF data threaded. This could be a SMRF issue.
