O aplicativo AlertaBlu oferece funcionalidades essenciais para o monitoramento de eventos críticos em Blumenau. Na tela inicial, você pode acompanhar, em tempo real, o nível do rio e o status atual, como: normalidade, observação, atenção, alerta e alerta máximo.

Você também pode cadastrar locais para monitorar: caso a rua cadastrada esteja em risco devido ao nível previsto, o app enviará um alerta diretamente para você. O AlertaBlu traz informações detalhadas sobre níveis do rio, enchentes, cotas, previsão do tempo, temperatura, barragens e escorregamentos, além de uma tela dedicada a notificações importantes.
