Steering currents at different pressure elevations. Not sure which to look at? How strong is the storm? Take a look at "Steering Layer ???-??? for TC MSLP of ???-???." If the cyclone has a pressure of 1010mb, the 700-850 might be more relevant. See "Product Interpretation" for more.

Has the wind shear lessened or become stronger over the past 24 hours?

This page also contains information about what shear we should expect this time of year and how much more or less shear there is compared to normal.
On the model page of our site, you can find links to various models. Some of those models may have an option to display the wind shear forecast over the forecast period. Here is one site that presents wind shear data: Fleet Numerical Meteorology and Oceanography Center (FNMOC). Another can be found by selecting the "Wind Shear" option on this page: Model Maps from Weather Underground
Note: As of November 23, 2009 the QuikSCAT satellite no longer provides real time data due to an instrument failure.
Marine Observing Systems Team (NOAA/NESDIS)
This site contains various surface wind techniques. Take a look at the options in the left column of the page. You'll see the following surface wind techniques and measurements under "Data Products": ASCAT (METOP-A), ASCAT (METOP-B), WindSAT and SSM/I. Some of the products have pages for active storms.
Surface Winds from NOAA CoastWatch Program
This site provides SSM/I imagery that allows you to select water regions that you want to view specific surface wind for. Regions are provided in alphabetical order. If you get to the page and see only Alaska imagery, use the arrow at the bottom of the page to continue to other regions. Sometimes it may take going through many pages. The latest image for each particular region is the last image shown. If you click the first "Gulf of Mexico" image you see, it is the oldest. Go to the last thumbnail before a new region is listed. It should, unless they change it, be the latest info. Look at the times under the thumbnails to see if you are selecting the latest image.

You have the ability to select the data you want and zoom in on it.

ASCAT and ERS-2 winds.
Navy / Naval Research Laboratory (NRL) Tropical Cyclone Page
Fleet Numerical Meteorology and Oceanography Center (FNMOC) Tropical Cyclone Page
These two pages are very similar. If you look at active storms in the left column, you will find surface wind imagery available at the top of the page. These pages have a lot of useful content.
A note about some of the sites above. Make sure you note the correct time the data was observed. Some times are simply when the image may have been created, such as the last time the system checked to see if info was available.

An updated version of the previous wind model images that were hard to read. This is an estimate of how far the wind will come inland with a landfalling storm. Every storm is different and higher wind speeds may of course be possible than those noted.
