Display Weather Alerts From NOAA Using Atom (WPF Example)

stormsample1So since there is this impending storm (blizzard, snow storm, snowmageddon, snowpocalypse, snowzilla) “Nemo” hitting us here on the East coast within a few hours, I figured a good topic might be on weather alert data. There is a bunch of data available from the NOAA (National Oceanic and Atmospheric Administration) on their site. Data is available in several categories, including ForecastsWatch/warningsStorm Prediction Center Forecast Products, etc. In my very quick example I’m going to pick the “Watch / Warning” data for my region and display this using WPF for an easy visualization.

Weather Alerts

In short, the process is: get the data using “ServiceModel.Syndication”, parse through, and display!


The Xaml:

<Window x:Class="wpfAlert.MainWindow"
        Title="Alerts" Height="319" Width="637" Background="#FFF1F1F1" WindowStyle="ToolWindow" SizeToContent="WidthAndHeight">

        <ScrollViewer Margin="10,41,10,27">

            <StackPanel x:Name="stkMain" Margin="10,10,10,10"/>

        <Label x:Name="lblStatus" Content="Refreshing..." HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" FontWeight="Bold"/>
        <Label x:Name="lblStatusBot" Content="Refreshing..." VerticalAlignment="Bottom" Margin="10,0,0,0"/>


The Code:

using System;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.ServiceModel.Syndication;
using System.Xml;
using System.Diagnostics;
using System.Timers;
using System.Windows.Threading;
using System.Windows.Controls;

namespace wpfAlert

    public partial class MainWindow : Window
        public MainWindow()

            //  The Refresh Timer
            DispatcherTimer dispatcherTimer = new DispatcherTimer();
            dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
            //5 Minutes
            dispatcherTimer.Interval = new TimeSpan(0, 5, 0);


        private void dispatcherTimer_Tick(object sender, EventArgs e)

        private void loadAlerts()


            Atom10FeedFormatter aReader = new Atom10FeedFormatter();
            using (XmlReader xmlReader = XmlReader.Create("http://alerts.weather.gov/cap/wwaatmget.php?x=NJC005&y=0"))

            int aCount = 0;

            foreach (SyndicationItem sItem in aReader.Feed.Items)

                //the alert summary
                TextBlock aTxt = new TextBlock();
                aTxt.Text = ((TextSyndicationContent)sItem.Summary).Text;
                aTxt.Width = 600;
                aTxt.VerticalAlignment = System.Windows.VerticalAlignment.Top;
                aTxt.TextWrapping = TextWrapping.Wrap;

                //a link to the entire alert
                Button aButLink = new Button();
                aButLink.Tag = sItem.Links[0].GetAbsoluteUri();
                aButLink.Width = 100;
                aButLink.Click += new RoutedEventHandler(alertLink_Click);
                aButLink.Content = "Alert Detail";

                //a panel to hold alert & link
                StackPanel aStk = new StackPanel();

                //title / expander
                Expander aExpand = new Expander();
                aExpand.Width = stkMain.Width;
                aExpand.Header = sItem.Title.Text;
                aExpand.Content = aStk;

                //add them to the form



            //update some label for info
            lblStatusBot.Content = aCount.ToString() + " Alerts Updated @ " + DateTime.Now.ToString();
            lblStatus.Content = aReader.Feed.Title.Text;

        private void alertLink_Click(object sender, RoutedEventArgs e)
            //handle links
            Button aLink = (Button)sender;



Obviously we can go so much deeper with this – radar, email, gps – but the purpose of this was to just share a quick / fun sketch.
