Raining in Obagi town today in Onelga , symbolize positive or negative.

Rain is nourishment for the earth and is known as the water of life.

I'll list the positives and the negatives and a bit of elaboration on both.

Positives:
Refreshment
The rain is refreshing after a drought or a period of scorching heat.

Life
Water is life. Rain brings an abundance of it bringing the dead and dry lands back to life. This is great in a story based around agriculture.

Anti monotony
Rain isn't exactly regular. It doesn't happen every day so that is another element.

Noah's Flood
There was vast rainfall in the biblical Noah's Flood so that can make a good paragraph on a story.

Negatives: 

Restriction/Imprisonment
If you go out in the rain, you get sick. This is common sense. So rain limits you to indoors. Thus, symbolising restriction.

Gloomyness
Rain has a natural gloomy feeling to it. A feeling that dulls emotions.

Cold
It can represent ruthless, inconsiderate, uncaring iciness. So that can be a great comparison to a character in a story, especially if it is raining at that time.

Noise
Rain makes a lot of disturbing noise when it comes crashing down. This now makes things harder.

Rain is the lifeblood of every Living Being and thus, a unique symbol of Intelligent Design of our Universe or Planet Earth. For example, it has not been found to rain in other planets; proving that the Earth is not a random happenstance but a deliberately, specially, and carefully thought out Big Garden for Living Beings: Of course with Humanity bearing overall responsibility for its sustainability.

Rain is a cooling, calming, and soothing system that counteracts the effects of other forces of nature like Sunshine to maintain an equilibrium or natural balance that sustains our Universe. Too much, we drown; and too little, we hunger, dry, and fry. Rain is a symbol of time, season, and a new beginning!!!!

The farmer, especially, knows that too well. Rain is also a symbolic guide to what then becomes our conscious, intelligent or rational choice and decision of where we live in the Desert or the Arctic! He always wins! That is the reason that HE is ‘The Intelligent Designer’. For example, without choice of abode and the power to make that choice, what is the point of free-will and fairness in personal responsibility for consequences of its exercise?! 

Rain, like other forces of Nature, is a constant reminder that we human beings are part of nature and thus can never be master of Nature- and that is not to discourage us from trying!: 

Rain makes no difference or distinction between the Queen or the pauper. Rain beats them alike and soaking wet. Thus rain ‘the leveller’ offers a great lesson that Social Justice must inform our public service planning and delivery! Rainfall being a public service and thus utilitarian! The subtle message there for you is always carry an umbrella or raincoat around because the rain will not make an exception of you! 

Rain can also be seen as a cleansing agent that purifies the atmosphere after some disaster. 

It has cleaned all the disaster in the Obagi community. So you can see how amazing rain is for both the good and the evil. 

As many who are witnessing the rain today, will surely  grow from death to live!

Good luck in your new environment.
