Current is not the same as possible later. A forecast describes what may develop. Treat a hazard as active when the official-alert section says a watch, warning or advisory is in effect.

Island Shield is an independent informational awareness tool, not an emergency service or official warning system. Data can be delayed, incomplete, inaccurate or unavailable. Do not rely on this dashboard as your only source of information or to decide whether to evacuate, travel or seek shelter. Follow public officials and official alerts. Call 9-1-1 for immediate danger and 2-1-1 for current shelter information. Use of the site is subject to the About Service Status Report a Data Issue Terms of Use and Privacy Notice.
Island Shield is independently developed and free for everyone to use. One-time or monthly support through Ko-fi helps cover live-data services, hosting, security, accessibility, maintenance and continued development.
The idea for Island Shield began with my grandparents, who have lived in Galveston their entire lives and have experienced many tropical storms and hurricanes. Whenever severe weather threatened the island, they often had to piece together information from television reports, phone alerts, government websites, social media and local news.
As they have grown older, that uncertainty has become more concerning to me. Preparing for a storm takes more time when mobility is limited, medications and important belongings must be gathered, pets need to be secured and transportation has to be carefully planned.
As a developer, I realized I could create something specifically for them: one simple place where they could see the information that matters without switching between multiple news channels, websites, apps and social posts. I wanted them to have access to clear, current information without having to navigate complicated technology or sort through rumors, sensational headlines and fear-driven content.
That is how Island Shield was created. It brings together available weather information, official alerts, tropical-system monitoring, causeway traffic, estimated travel times, shelter resources and other safety information in one accessible dashboard so people can prepare earlier and feel more confident about the decisions ahead.
Now I want to make Island Shield available to everyone in Galveston, free of charge, and eventually expand the same approach to other coastal communities that face similar challenges.
Roughly $1,500 per month helps keep Island Shield online, responsive, improving and available when the community needs it most.
