DESCRIPTION ^

This module reimplement Weather::TW with new web address (from V6 to V7) and new parser (use Mojo::DOM instead of HTML::TreeBulder). The methods in Weather::TW will be deprecated and shiped to Weather::TW::Forecast. More submodules will be develop to handle obsevations and detail rain infos. Weather::TW will be a abstract class to access these submodules.
