This app will update user via text when it will rain within the next 4 days. Per Environmental Pollution Agency (EPA), dischargers such as manufacturing companies are required to sample each rain event (at least twice every 6 months) and execute the proposed Best Management Practice. Because it does not rain as often at some places, especially Los Angeles, dischargers could lose track of the upcoming rain event. Missing a sampling event could become an issue for dischargers since that is a regulatory requirement. It is especially important for the dry regions since missing one event could put the company at risk of a regulatory violation.

Though the motivation of this app was driven by the regulatory purpose, this could be used to remind the users of the rain event as well.
