Interesting Windshield Crack
As you may know, Texas has been suffering some severe weather lately. We, over in the west side of the state, have fortunately been less impacted than the central and eastern portion. The storm fronts usually start building over here, and get progressively stronger as they move east. However, yesterday we got a little taste of the bad stuff. Big super cell storm blossomed right on top of us with heavy rain, high winds of course, several reports of tornadoes on the ground near the airport (between Midland and Odessa), and lastly my favorite: large damaging hail.
Our coach sits out in our driveway unprotected. Been there (when not traveling) for about 11 years, and up to now no weather related damage. During this storm the wind was blowing out of the north at over 80 MPH, and the hail was coming down from that direction. Our coach sits facing north, so the front end was exposed to the worst of the wind and hail. After the storm moved on, I went out to survey damage. Almost everything on the coach roof survived perfectly intact, except two of the amber running lights above the windshield were smashed. At first I thought the windshields were undamaged, but taking a closer look I saw a crack in the passenger side glass.
The crack follows a round track, and covers about 190 degrees of a almost perfect circle. It appears to originate at a small chip in the glass. The chip may have been there previously - I can't recall for sure. I am sure the crack was not there before. Looking at the outside of the windshield, I can't feel the crack with my finger tip or my finger nail. Standing inside the coach, I can't feel anything, but that's expected because our coach has the ceramic heat blocking film on the inner windshield glass.
Tried to get some photos (below) but the camera has a hard time focusing on the crack.
Anyway, a quick Google search tells me this type of damage is very unusual. It doesn't look at all like other photos of hail damage. I ASSUME it was caused by the impact of a big hail stone. We saw stones larger than golf balls falling in our yard, and they reported baseball and softball sized hail at the airport 7 miles SE of our house. Just wondering if any other Forum members have ever had this peculiar type of glass damage.
We have Progressive zero deductible windshield coverage, so I'll get the glass replaced eventually. Not looking forward to the hassle of finding a place to do the job properly. I've read all the past horror stories on the Forum. Anyway, I don't feel like it's an emergency so I'll take my time getting around to that project.
