The National Meteorological Office issued alerts today (10/22/12) for several towns due to saturated ground and a tropical wave that will be coming through today. Barahona, Azua, Bahoruco, Pedernales, Independencia, San Juan de la Maguana and Elías Piña provinces were all among towns in the weather alert.
This latest storm is expected to cause rivers and streams to rise and possibly bring floods and landslides to the affected areas. Along with the rain, thunderstorms are expected.
The Dominican Republic has some of the most impressive thunderstorms I have ever seen. I like to sit out on the (covered) deck and watch the storm go past. But, along with a good light show, is a greatly increased chance of damage to your inversor (inverter), power regulator, batteries and other electrical equipment in the house.
I have a cut off switch for my house where I can disconnect the incoming power line (whether we are currently getting power or not) before it reaches any of my equipment to protect them from power surges. These storms have in the past either came in faster than I expected or happened while I was out of the house and I ended up needing to do a bunch or expensive repairs, so I am pretty diligent about using this switch now.
If you haven’t got one installed it’s a good idea to do so. All you need to do is put a double pole, single throw, knife switch in line with your incoming power which you pull down when a heavy storm like the one that caused this alert, passes. A little prevention can save you a day or two without battery backup while you inversor gets repaired as well as quite a bit of expence.
