Harvey Help
Over the week I have shared resources that can help the insurance industry understand the impact from Hurricane Harvey. Now that Harvey is moving slowly inland, with smaller creeks receding and damage assessments beginning, I would like to summarize and share more resources that will help the insurance industry understand Harvey’s impact.

As previously mentioned, BMS clients and prospects have access to several tools that may help understand the various impacts of Hurricane Harvey via the BMS iVision Geospatial Mapping Solution. These products are available across various geographic regions, including the Gulf Coast, with storm attributes that include hurricane and severe weather perils that often accompany a hurricane. Users can intersect these attributes with policies at risk to get an idea of exposure and apply damage ratios as a first guess at potential losses.

• Hurricane past and forecasted track, sustained winds and wind gusts
• Hail size, probability and duration
• Severe Thunderstorm winds, radar max and rainfall

Of course it is possible to add other data attributes to iVision as needed and that has been done for specific users. Outside of BMS iVision, there are several great sources that have appeared to help understand Harvey’s impacts.

Harvey Wind Damage Resources
The NOAA Remote Sensing Division has provided high resolution airborne imagery to support NOAA national security and emergency response requirements. These images have been combined into a larger mosaic and tiled for distribution. The approximate ground sample distance (GSD) for each pixel is 50 cm / zoom level 18.

Detailed FEMA Flood Zone Mapping of the Houston Area

U-Flood is a crowd sourced effort to map inundated roads in Houston. Flooded (or cleared) streets may be reported by zooming into the map and clicking/tapping them.

Other Tropical Troubles
As I mentioned in Monday’s post, a new tropical wave has been named (Irma) in the Main Development Region of the Atlantic and will track toward the U.S. coastline. Irma is still 10 days away, but given the pattern so far, the chances of a U.S. tropical threat late next week are high, but there is still a lot of uncertainty in the pattern as a major cool down for the east coast next week will likely play a role in Irma’s future track. I will provide new updates on this threat as it develops.
