The model is initialized with a restart file from the Puerto Rico Analysis and Assimilation configuration and does not cycle on its own states. The Puerto Rico Short-Range open loop deterministic forecast configuration is executed two times per day using the same forcing as the Puerto Rico Short-Range standard configuration, but drawing initial conditions from the Puerto Rico Open Loop Analysis and Assimilation.
A full breakdown of output file contents can be found here. Output from the National Water Model is currently visualized on this website using the experimental interactive map , and the experimental image viewer.
The exception are the channel output files containing streamflow and other variables representing processes along river reach segments. To support visualization of these variables, the latitude and longitude coordinates of the centroid of each reach are made available in a separate ESRI file geo-database gdb , outside of the NWM outputs. The file gdb can be used in many common GIS software utilities to attach coordinates to the data. The file gdb is available here. NCEP encourages all users to ensure their decoders are flexible and are able to adequately handle changes in content order and also any volume changes which may be forthcoming.
These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes prior to any implementations.

Analysis and Assimilation Configurations: Standard Analysis and Assimilation The Standard Analysis and Assimilation configuration cycles hourly and produces a real-time analysis of the current streamflow and other surface and near-surface hydrologic states across the contiguous United States CONUS. Extended Analysis and Assimilation The Extended Analysis and Assimilation configuration cycles once per day and produces an analysis of the current streamflow and other surface and near-surface hydrologic states across the contiguous United States CONUS.
Long-Range Analysis and Assimilation The Long-Range Analysis and Assimilation configuration cycles hourly and produces a real-time analysis of the current streamflow and other surface and near-surface hydrologic states across the contiguous United States CONUS , using higher quality precipitation data than is available to the Standard Analysis and Assimilation. Hawaii Analysis and Assimilation The Hawaii Analysis and Assimilation configuration cycles hourly and produces a real-time analysis of the current streamflow and other surface and near-surface hydrologic states across the Hawaii domain.
I have just had a birthday and I am entitled to a higher rate, when should the new rate apply? The accommodation offset rate is amended on 1 April every year. What are some problem areas? We look at some of them here: Training time Where workers undergo training for example — employment induction or skills development , the time spent on such activities is working time for minimum wage purposes where a contract of employment has started or where it is a contractual requirement for the worker to attend the training.
Example Wali is 35 years old and is paid weekly. Interns Any intern who has a contractual relationship with his employer must be paid at least minimum wage for the hours they have worked. Example Carry aged 19 is paid weekly. Salary sacrifice Under a salary sacrifice arrangement , an employee is able to swap cash salary for non-cash benefits like pension contributions, cycle to work or childcare vouchers closed to new recipients from October Example Neena, 38, works as a cleaner.
Other areas There is a comprehensive employer guide to calculating the NMW and NLW produced by the BEIS that you may find helpful as it covers other complex topics like salaried workers and sleeping in time.
