Description

* NOAA Hurricane Tracking and Forecast Data * MAIN FEATURES INCLUDE: * NHC GOES-16 Satellite Imagery * 5-day Hurricane Forecast / Tracker * 5-day Tropical Storm Outlook (Pacific) * 5-day Tropical Storm Outlook (Atlantic) * NWS Tropical Weather Discussion * Storm Specific Forecast & Public Advisories * Wind History, Rainfall Forecast & Flash Flood Risk Graphics By far the fastest, most convenient way to access National Hurricane Center data. The app displays detailed satellite imagery animations, allowing you to track the storm using the most recent observations. There are 10 filters in total, letting you view the storm from unique perspectives. More satellite filter details below: -- Band 2 -- 0.64 µm - 'Red' Band - 0.5 km resolution - Visible band 2 is in the red portion of the spectrum and has the highest resolution of any ABI band at 0.5 km, and for that reason is the primary visible band. It is used primarily to monitor the evolution of clouds throughout the daylight hours. -- Band 4 -- 1.37 µm - 'Cirrus' Band - 2 km resolution - Band 4 will detect very thin cirrus clouds during the day. This band is centered in a strong water vapor absorption spectral region. It does not routinely sense the lower troposphere, where there is substantial water vapor, and thus provides excellent daytime sensitivity to high, very thin cirrus under most circumstances. -- Band 5 -- 1.6 µm - 'Snow/Ice' Band - 1 km resolution - During the day band 5 can be used to differentiate ice clouds and snow (relatively dark) from liquid water clouds (relatively bright), such as fog and stratus. It can also detect very hot fires both day and night. -- Band 7 -- 3.9 µm - 'Shortwave Window' Band - 2 km resolution - Band 7 has a variety of applications, including fire detection, cloud particle size retrievals, and differentiating between liquid water and ice clouds. Fire hot spots will show up as relatively small dark gray to black pixels. GOES-16 band 7 corresponds approximately to the old GOES-13 infrared channel. -- Band 8 / 9 / 10 -- 6.2 µm - 'Water Vapor' Bands - Band 8 will be used for upper-level tropospheric water vapor tracking, jet stream identification, hurricane track forecasting, mid-latitude storm forecasting, severe weather analysis, upper mid-level moisture estimation (for legacy vertical moisture profiles) and turbulence detection. The imager on GOES-16 features three mid-level water vapor bands instead of the single water vapor band on the GOES-13 Imager. The single water vapor band on GOES-13 contained a mixture of water vapor features over many levels of the troposphere, but GOES-16 enables us to focus on water vapor in the upper troposphere (band 8), the middle troposphere (band 9), or the lower troposphere (band 10). -- Band 13 -- 10.3 µm - 'Clean' Longwave IR Window Band - Band 13 at 10.3 µm is an infrared window, meaning it is not strongly affected by atmospheric water vapor. This channel is useful for detecting clouds all times of day and night and is particularly useful in retrievals of cloud top height. -- Band 14 -- 11.2 µm - IR Longwave Window Band - the traditional longwave infrared window band, is used to diagnose discrete clouds and organized features for general weather forecasting, analysis, and broadcasting applications. Observations from this IR window channel characterize atmospheric processes associated with extratropical cyclones and also in single thunderstorms and convective complexes. -- GEOCOLOR Band -- Geocolor is a multispectral product composed of True Color during the daytime, and an Infrared product that uses bands 7 and 13 at night. During the day, the imagery looks approximately as it would appear when viewed with human eyes from space. At night, the blue colors represent liquid water clouds such as fog and stratus, while gray to white indicate higher ice clouds, and the city lights come from a static database.

    This app will definitely keep you informed of anything that might be popping up & keep you up to date with what might be happening out there.

    Satellite images are from January although active system is Alberto. Couldn’t contact dev, as app crashed when touching contact icon. 30MAY18 - Developer very responsive; corrected issues. Rating edited.
  • Not as good as Hurricane Pro.

    Hurricane pro was cancelled. Loved it. Got this for a replacement and it’s just not as good. But it will do until something else comes around!
  • App is getting better all the time.

    I wrote an earlier review that was less than positive. Soon after I was contacted by the developer. He is working hard to make this app one of the most useful hurricane tracking apps available. One update has been added; another is on the way which allows users to keep informed with potential storm developments. We’ll check back here again when there is a named storm. Thanks for the improvements. The developer’s willingness to listen constructively is an added bonus! Go to Settings and find a direct link to the National Hurricane Center website. This is a real plus. This app just keeps getting better.
  • Add Forecast Discussion and Advisory Text?

    Can you add buttons to link to the text details from NHC forecast advisories and discussions, and public advisories - for each of the current storms? That would make this the 5 star must have app for hurricanes!! Update: a few hours later the text advisories and discussions are in an app update. 5 stars now.
  • Best hurricane tracker out there

    I’ve been using the NHC website ever since I moved to FL and finally decided to get the app. It’s everything I could have wanted in a hurricane tracker and more. Gives you tons of info, tracking, satellite, and it’s all easily navigable. Love it!
  • Did not get money’s worth

    I don’t see the different screens that are shown on the App Store page. Just still imagery tracking. No motion satellite. Are there push notices? I was looking for an active app that helps prepare for hurricanes. I can go to the NOAA website and get more info. Very misleading to use the NHC name.
  • Nothing Loads

    This app doesn’t work and is way too slow to actually be with while. I want my money back...,
  • Not worth $1.99

    Tropical storm in gulf and I am looking at satellite imagery from January. I am better off just going to the web site.
