New Storm List and Outlook Map
There has been some confusion over the new storm list and the outlook map which was added to the top of the storm list. Each year, we hear from our customers,
and they would like more information – a brief look at what is going on – when they open the app. To that end, we added the NHC Outlook graphics to the top of
the storm list to give you a brief view of what we’re watching in a particular ocean area. Swipe the image to see other images, special messages about
storms or the app. The rest of the storm list works the same way as it always has, a brief summary of information is on the storm item, tap on it to open the
interactive map, storm centered satellite image, radar, advisories and forecasts.

Push Alerts
Push alerts happen when a significant change happens to a storm.
Odds are, if you are in front of a storm, you know the storm is there and are watching local media outlets for that storm.
You can turn off alerts for oceans you do not want to be alerted for. The alerts are available by basin, or ocean area: Atlantic, East and Central Pacific, and the rest of the World. To this end, we will be very selective about our alerts, ensuring that the message gets out to those who need it, and attempt not to disturb those who do not.
If you would like to change your push notifications settings, tap the menu button at the top left of this page, then select Map and Push Settings to change your settings.
If you would like to turn sounds off on your device, go into Settings > Notifications > Hurricane Pro > Sounds – turn the switch off. There is also a switch for alerts in this location as well.

How do I refresh current storms?
If you are looking at the map, go back to the storm list, and the data should be refreshed automatically every 2 hours or so. If you would like to check for new storm plots, press the refresh button at the top of the storm list page. The bottom of the storm list page will show you if there is a new video available, and what time (local to your device) the storms were last updated from our servers. Many pages have the ability to be refreshed individually with the refresh button including all Satellite, Radar, Forecast and Bulletin pages.

Data does not refresh
From time to time, you may find that the data does not seem to refresh. Hurricane automatically checks for updates every two hours, but if you would like to check manually, you can pull down on the storm list, the last time the refresh took place will be listed in the newly shown area. Hurricane uses A LOT of memory for the data and display on the maps. If you find that there is an update, and the data still does not refresh, close Hurricane completely and restart. Closing other currently running apps (you may have A LOT of them that you haven’t touched in DAYS) or rebooting your phone will also solve this problem.

Wind Radii
Our forecast maps also contain wind radii information for the forecast plots. The colors below correspond to the colors of the wind radius.

How to Refresh a storm manually… Refreshing, or getting new storm data is actually really easy. The app will automatically
grab the latest data every 2 hours, however there are times that you may want to check back for new data – like if you open up the app right before a new storm
bulletin or plot becomes available. Simply go to the Storm Name List, and press the refresh button. You’ll see text on the bottom of the storm list telling you when the
refresh last happened, right next to the video icon, which also shows you when there is a new video available.

About Satellite Refresh… Images are obtained the first time you view satellite or other data images. While inside the application after viewing the first time, refreshing the page will give you an updated image only if one is available from the official source. Radars usually update every 5 minutes, and satellites can refresh anywhere from 1/2 hour to 3 hours depending on the source.

How to open Notification Center… The iOS Notification Center was a new feature in iOS 5. With that update, you are now able to pull down from the date/time bar and see the notification center. In the notification center you will not only see our push notifications, but you will also see those for other apps as well. Most of the time our push notifications are centered around a coming storm, so reading the Text Advisory from the National Hurricane Center will usually give you that same information we wanted to make sure you were alerted to.

Australia and Southwest Pacific

About Public Advisory Update Times… A few of the AppStore reviews mention that they would like better than 6 hour updates
for storm systems. We rely on data from the National Hurricane Center, and are therefore on their schedule, along with every other news agency. If you are
in the path of a storm, you should consider Hurricane Pro and Hurricane HD “nice to have”, but your local media outlet (TV/Radio/NWS Weather Radio) is
what you should be viewing for your local information from emergency managers and agencies.

With that being said, if our storm was on bulletin #21, this is how the National Hurricane Center would show their public bulletins and forecast advisories:

• Forecast/Advisory and Public Bulletin (21, 22, 23)
  Published every 6 hours by the National Hurricane Center.
• Intermediate Public Advisories: Issued by the National Hurricane Center whenever watches or warnings are in effect. Intermediate advisories are position updates,
  which also contain the very important updated watch and warning information. Forecasts and wind radii are not published with intermediate advisories.
  • 3 hours after regular advisory (21, 21a, 22, 22a)
    
    The National Hurricane Center will upgrade to “a” bulletins (21a, 22a) whenever watches or warnings are in effect.
  • 2 hours after regular advisory (21, 21a, 21b, 22, 22a, 22b)
    
    The National Hurricane Center will upgrade to “a” AND “b” bulletins issued every 2 hours whenever watches or
    warnings are in effect and there is a clear center of circulation (eye) observable on radar.

Tropical Storm Watch:
An announcement that tropical storm conditions (sustained winds of 39 to 73 mph) are possible within the specified coastal area within 48 hours.

Tropical Storm Warning:
An announcement that tropical storm conditions (sustained winds of 39 to 73 mph) are expected somewhere within the specified coastal area within 36 hours.

Hurricane Watch:
An announcement that hurricane conditions (sustained winds of 74 mph or higher) are possible within the specified coastal area. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 48 hours in advance of the anticipated onset of tropical-storm-force winds.

Hurricane Warning:
An announcement that hurricane conditions (sustained winds of 74 mph or higher) are expected somewhere within the specified coastal area. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane warning is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.

Rapid Intensification:
35 mph wind increase in 24 hrs.

Post-Tropical Cyclone:
A former tropical cyclone. This generic term describes a cyclone that no longer possesses sufficient tropical characteristics to be considered a tropical cyclone. Post-tropical cyclones can continue carrying heavy rains and high winds. Former tropical cyclones that have become fully extratropical, as well as remanant lows, are two specific classes of post-tropical cyclones.

Remanant Low:
A post-tropical cyclone that no longer possesses the convective organization required of a tropical cyclone, and has maximum sustained winds of less than 34 knots. The term is most commonly applied to the nearly deep-convection-free swirls of stratocumulus in the Eastern North Pacific.

Extratropical Cyclone:
A cyclone of any intensity for which the primary energy source is baroclinic (that is, results from the temperature contrast between warm and cold air masses).

Understanding Storm Surge…Along the coast, storm surge is often the greatest threat to life and property from a hurricane. In the past, large death tolls have resulted from the rise of the ocean associated with many of the major hurricanes that have made landfall. Hurricane Katrina (2005) is a prime example of the damage and devastation that can be caused by surge. At least 1500 persons lost their lives during Katrina and many of those deaths occurred directly, or indirectly, as a result of storm surge. Read More
