Tropical storms, which can develop into hurricanes, typhoons, or cyclones, pose significant risks such as heavy rainfall, strong winds, and potential flooding. The northwest Pacific is the most active region, averaging 25 named storms annually, while the Atlantic sees about 14 per season. These storms can disrupt daily life, damage infrastructure, and threaten safety, particularly in coastal and low-lying areas. RainViewer's live radar and notifications aim to mitigate these risks by providing timely updates and accurate tracking.
