%description
The Ditwah storm began impacting Sri Lanka on 25 November 2025. Ditwah
provides a collection of tidy, well-structured datasets to support storm
data management, monitoring, and early warning applications in Sri Lanka.
The publicly available data were converted to tidy data format for easy
analysis. The package processes weather data, flood data and situation
report data (families affected, etc.). The package also includes functions
for analyzing river level progression and load dashboard visualizations to
enhance situational awareness. This is also developed for educational
purposes to support learning in data wrangling, visualization, and
disaster analytics.
