Sacramento could get 4-plus inches of rain, wind gusts up to 50 mph

“Gusty southerly winds are forecast across interior NorCal Thursday afternoon through Friday afternoon creating difficult driving conditions, downed branches, and possible power outages,” tweeted the NWS Sacramento office on Wednesday. “Secure your outdoor objects and drive with caution in/around high-profile vehicles!”
The weather service also issued two weather alerts: A flood watch from 1 p.m. Thursday through 9 a.m. Sunday and a 24-hour high-wind advisory, starting at 4 p.m. Thursday.
This atmospheric river is tropical in origin; that means more rain than snow in the Sierra. However, that rain could melt snow at lower elevations, adding to flood risk, says the weather service. The flood watch extends from the Sierra foothills to Suisun Bay.
All this wind and rain puts big trees – particularly evergreens – at risk. Some redwoods, cedars and firs are already battered by a very active winter. If another branch is ready to break, this may be the weekend it comes down.
Beware of leaning trees. Their roots may be giving way. Our soil is already moist and soft; that makes it slippery, too. Sacramento received more than a half inch of rain in the series of showers that started March 4. That will seem like a puddle compared to the expected deluge.
The current forecast predicts 4.4 inches of rain between noon Thursday and Tuesday evening. But instead of chilly nights and days in the 40s, our temperatures will be near or above normal. Afternoon highs will hover in the low to mid 60s. The biggest change is overnight lows. Instead of near freezing, nighttime temperatures will stay mostly in the 50s.
Those higher overnight temperatures will help warm soil and speed spring growth. A lot of plants will appreciate all this moisture.
In the meantime, tie down the patio furniture. Clear gutters and storm drains of any debris. Move potted plants (especially succulents) to sheltered locations. All that rain can rot succulents as well as seedlings.

Garden Checklist for week of April 21
This week there’s plenty to keep gardeners busy. With no rain in the immediate forecast, remember to irrigate any new transplants.
* Weed, weed, weed! Get them before they flower and go to seed.
* April is the last chance to plant citrus trees such as dwarf orange, lemon and kumquat. These trees also look good in landscaping and provide fresh fruit in winter.
* Smell orange blossoms? Feed citrus trees with a low dose of balanced fertilizer (such as 10-10-10) during bloom to help set fruit. Keep an eye out for ants.
* Apply slow-release fertilizer to the lawn.
* Thoroughly clean debris from the bottom of outdoor ponds or fountains.
* Spring brings a flush of rapid growth, and that means your garden is really hungry. Feed shrubs and trees with a slow-release fertilizer. Or mulch with a 1-inch layer of compost.
* Azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.
* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.
* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.
* Mulch around plants to conserve moisture and control weeds.
* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, radishes and squash.
* Plant onion sets.
* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias.
* Transplant petunias, zinnias, geraniums and other summer bloomers.
* Plant perennials and dahlia tubers for summer bloom.
* Mid to late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.
* Transplant lettuce seedlings. Choose varieties that mature quickly such as loose leaf.
