No Deaths, But Another Disaster Might Now Be Hitting The South

Peach blossoms like this might be damaged or destroyed in a
widespread hard freeze going on in the South this week. A large
percentage of this year's crop might be ruined. 
It's kind of hard to tell right away, but another big disaster might be hitting the South, the second one this week.

As we know, tragic tornadoes killed 23 people and caused widespread property damage Sunday, especially in Alabama and Georgia.  

This new disaster now unfolding very likely won't kill or physically injure anybody. No additional houses will suffer structural damage. But this latest weather event could prove pretty expensive.

Freeze warnings stretch this morning in a broad band from Texas to South Carolina. It was below freezing, with some areas of reporting record chill this morning. More hard freezes are forecast tonight and in some places, tomorrow night.

It's especially harsh in areas hit by the tornadoes. In Lee County, Alabama, the epicenter of the tornado disaster, some sleet was reported overnight, and temperatures were in the mid-20s this morning.

Across much of the South, especially east of the Mississippi River, it was a near-record warm February. That prompted a lot of crops, including big fruit tree farms to start budding and blooming much earlier than normal.

Then this blast of Arctic air hit. If this sounds familiar, it's because it is. Similar expensive freezes after record early season warmth  hit parts of the middle, southern and eastern parts of the nation in 2017 and 2018.

In the Texas hill country, a big area around Austin, peach trees were blooming. If the temperature falls to 28 or lower for a fairly extended period of time, you lose the entire peach crop once the flowers are blooming. That's the scenario Texas peach farmers are now facing. 

Early this morning, it was 26 degrees in Austin, Texas and 29 in San Antonio. Remember: It's usually a bit warmer in the cities than in rural areas, where the peach trees are.

In North Carolina, early varieties of peach trees are blooming, so those could be wiped out. On the bright side, later varieties of peach and apples aren't far enough along yet in North Carolina to suffer much harm. The cold will also slow down growth in those trees, so subsequent freezes later this month might not cause as much damage.

The situation is a little more dire in further south in South Carolina and Georgia, where peaches and other fruits have progressed along more than up in North Carolina.  Peach blooms are about two weeks ahead of schedule in South Carolina.

The freeze is in progress, so it won't be clear how much damage there is until days after the freeze ends, at least.

This isn't the type of weather disaster or event that garners headlines, like dramatic storms do, but worst case scenarios can cause many tens of millions in damages for farmers. Crop insurance helps, but it's not a cure all.

For the few of you who might be worried about how this will affect the famed cherry blossom spectacle in Washington DC, the short answer is, it won't. It is cold in Washington this week, with forecast temperatures to get as low as 20 degrees tonight and tomorrow night.

But the cherry buds are not nearly far enough along to suffer damage from the cold blast. Peak bloom in Washington is usually in late March or very early in April.
