# Pysteps nowcast with west Africa precipitation data.
Nowcast is a short-term weather forecast, which only predicts the weather change within 6 hours from the start point.
All the nowcasts in this project based on the installation of Pysteps.
pysteps.readthedocs.io
The first thing of first, find a good place to store the Precipitation data on 20210522.
Second, in order to feed the data into "STEPSs nowcast.py". Go to the pystepsrc and modify your "rootpath" , the data tag is at the bottom of the "pystepsrc". Now your new configuration file is ready, you can copy and paste it to replace your default "pystepsrc".
Remember, importers.py should be put in your "io" file (within your Pysteps file)to replace the old one, otherwise the Pysteps can only plot the map of example data which come along with Pysteps when you download it.
STEPs, verification and evaluation, and strom tracking are the main py files to yield the results.
Everything seemed to be set,now you can try on:)
