We are a Financial Services company. We would like to leverage ESRI GIS Technology to assist our customers impacted due to natural disaster events.

We are looking for:

1. Live tracking of Hurricanes
2. Flood map with in 24 hours of such event.
3. Tornado/Earth Quake maps with in 24 hours of such event.

We are using ESRI ArcGIS technology. So, it would be beneficial to get the SHAPE Files for the above.

Are there any subscription services available to get this information ? Are there any agencies you would recommend ?
Of course, we would like to make sure it is accurate and official since we will be making decisions using this data.

Would appreciate if you could point us to right direction. Thanks in advance.
