WEATHER UPDATE: The risk of flash flooding will continue across the islands this weekend as a kona storm moves through the region
Our take
As we gear up for the weekend, the islands are preparing for a kona storm that brings with it the risk of flash flooding. With the surface low now moving north, we can expect bands of moderate to heavy rain, sometimes accompanied by thunderstorms, to sweep across the state. This weather scenario is not just a meteorological event; it serves as a reminder of the dynamic nature of life in Hawaii. As noted in our previous articles, including WEATHER UPDATE: A final round of moderate to heavy rain will move across the islands on Sunday and Monday before more favorable conditions settle in for the rest of the week and WEATHER WATCH: The potential exists for more heavy rain and flooding next week as a series of upper-level disturbances drags across the islands, weather patterns in our region can have profound effects on our daily lives and the environment.
As we approach Monday, the hazardous weather will gradually taper off, but the risk of flash flooding will linger. Understanding the implications of this ongoing weather system is crucial. The National Weather Service has indicated that while the risk of further flooding from rainfall is currently low, the situation remains fluid, particularly with conditions at the Wahiawa Dam. This highlights the interconnectedness of our ecosystems and the importance of being vigilant as we navigate through these weather patterns. For residents and visitors alike, the potential for localized flooding can disrupt plans and impact the enjoyment of our beautiful island lifestyle.
Looking ahead, the forecast suggests a shift to a 'wet trades' weather pattern starting Tuesday. This transitional phase will bring scattered to numerous windward showers, setting the stage for a typical trade wind regime. This is the essence of the Hawaiian experience—the ever-changing weather that adds layers of excitement and unpredictability to our lives. The interplay of rain and sunshine creates a vibrant landscape, fueling not just the natural beauty that draws many to our shores but also the local culture that thrives on such diversity. It's a reminder to embrace the unexpected and find joy in the rhythms of island life.
As we navigate this weather update, it's essential to consider how these changes impact not only our daily routines but also the broader community and environment. With each storm system, we have an opportunity to reflect on our relationship with nature and the importance of sustainability. Community resilience becomes paramount during these times, as residents come together to support one another and share resources. It’s a call to action for all of us to be informed and prepared, ensuring that we can fully enjoy the treasures our islands have to offer.
In conclusion, while we may be facing some wet weather, let’s remember that it's just a chapter in the ongoing story of life in Hawaii. As we look forward to the stabilization of conditions later in the week, we invite you to explore the unique experiences that come with our diverse climate. Whether it’s indulging in the lush landscapes that flourish after a rain or savoring the vibrant local cuisine that captures the essence of our culture, let’s embrace the adventure that lies ahead. How will you make the most of this weather transition?
Updates
As of 4:30 AM HST on Sunday:
The surface low associated with the kona storm is now well to the north of the islands.
Several bands of moderate to heavy rain, with some embedded thunderstorms, continue to move slowly eastward across the islands this morning.
Hazardous weather will slowly taper off today, though the risk of flash flooding will continue into Monday.
A 'wet trades' weather pattern will settle into the area on Tuesday and will continue through the weekend.
Forecast synopsis
From the National Weather Service office in Honolulu:
As of 3:19 AM HST on Sunday:
A surface kona low pressure system continues to meander northeastward away from the Hawaiian Islands, producing bands of moderate to heavy showers and embedded isolated thunderstorms across much of the state, namely Maui County and the Big Island. As the system exits the vicinity of the islands, a broad area of high pressure fills in its wake Monday, allowing trades to return from west to east, persisting through the remainder of the week. Windward showers will initially be scattered to numerous Monday, but will decrease to a more typical trade wind regime with isolated to scattered showers across windward and mauka areas.

- WEATHER UPDATE: A final round of moderate to heavy rain will move across the islands on Sunday and Monday before more favorable conditions settle in for the rest of the weekBackground As of 6:00 AM HST on Sunday, April 12: An upper-level trough approaching the islands from the northwest has restarted the flow of deep tropical moisture over the islands this morning and will likely lead to several bands of moderate to heavy rain showers and a few thunderstorms over the next couple of days. The heaviest rain will likely set up over Oʻahu and Molokaʻi today and will slowly retrograde back toward Kauaʻi on Monday. Later in the week, light trades will develop, but conditions will remain warm and very humid until stronger trades set up midway through the following week. The National Weather Service has extended the Flash Flood Watch until Monday afternoon, as the ground remains saturated from recent heavy rainfall. Key points As of 6:00 AM HST on Sunday, April 12: On Sunday, the heaviest rainfall will likely impact Oʻahu, Molokaʻi, and Lanaʻi. On Monday, the heaviest rainfall will shift back toward Kauaʻi. Maui and Hawaiʻi will largely avoid the worst impacts, but flash flooding is still possible with afternoon showers. Conditions will slowly improve on Tuesday, with light trades setting back up. Warm and humid conditions will continue through early next week. Forecast synopsis As of 3:49 AM HST on Sunday, April 12: From the National Weather Service office in Honolulu: Showers and isolated thunderstorms will spread over the western half of the state becoming heavy over central portions of the state through tonight. The heaviest rain bands are anticipated over Oahu and Molokai, and possibly spread westward over Kauai. Because of the latest rainfall over the last few days, flash flooding is possible. Light and variable winds are expected to prevail through the first half of the week, with light trades returning to the state thereafter.

- WEATHER UPDATE: Another kona storm may bring periods of moderate or heavy rain throughout the week, bringing renewed concerns for flooding across the islandsKey points As of 9:00 AM HST on Monday, April 6: Monday: Winds will begin to weaken and shift to a more easterly to southeasterly direction. Isolated rain showers are possible, particularly over windward and mauka areas. Tuesday: Winds will shift to a more southerly direction, pulling abundant moisture up from the deep tropics. Isolated rain showers are possible, particularly over leeward and mauka areas. Isolated downpours are possible over areas of higher terrain. Wednesday through Friday: An area of low pressure is likely to develop to the northwest of Kauaʻi on Wednesday. A series of upper-level disturbances will move across the islands over the next few days. Instability from these disturbances combined with the added moisture will result in periods of moderate to heavy rain, which could lead to flash flooding. Upcoming weekend: Rainfall intensity may decrease over the weekend, but the threat of flash flooding could continue as the ground will remain saturated from the accumulated rain from earlier in the week. Early next week: Long-range model guidance suggests that a second system could set up directly behind this storm, so impacts could continue into the upcoming week. Forecast synopsis As of 9:49 AM HST on Monday, April 6: From the National Weather Service office in Honolulu: Mostly dry and pleasant trade wind weather will continue today, with brief passing showers favoring windward and mauka areas. A significant pattern change is then expected by Tuesday as an upper disturbance and surface low pressure evolve northwest of the islands. This system is expected to draw deep tropical moisture northward over the state, leading to an extended period of southerly winds, increased chances for widespread rainfall, and renewed flooding concerns from from the middle of the week through the weekend.

- WEATHER WATCH: The potential exists for more heavy rain and flooding next week as a series of upper-level disturbances drags across the islandsKey points As of 9:00 PM HST on Thursday, April 2: A series of upper-level disturbances may move across the islands next week. These systems will pull abundant moisture from the deep tropics to the islands. The potential exists for heavy rain and flooding across the islands starting as early as Tuesday. As with the previous two kona storms, rain from this event could last for several days. It remains too early to determine the exact timing and extent of this rainfall event. Forecast synopsis As of 3:45 PM HST on Thursday, April 2: From the National Weather Service office in Honolulu: Early next week, the first of a potential series of upper level troughs will move by north of the state. This will shift low level winds around to SE and start to bring increased moisture from the south. Tuesday into Wednesday, the moisture appears to increase enough to significantly raise the chance of moderate to heavy rain over the area, and winds may become southerly. There is still a good deal of model spread on how strong this next potential system will be and how much rain may be headed our way. However, the potential for heavy rain and flooding is there, and this will be watched carefully. Confidence in the forecast will increase, as always, as we get closer in time. Please keep yourself updated through the weekend for the latest forecasts. Weather risk outlook As of 9:00 PM HST on Thursday, April 2: A risk outlook has not yet been produced by NWS Honolulu.

- WEATHER UPDATE: Conditions will gradually improve as a cold front moves eastward across the islands today, but additional rain is possible on Sunday and MondayBackground As of 6:00 AM HST on Friday, April 10: We are approaching the end of the worst impacts expected from this storm system. Analysis of satellite and radar imagery shows that a cold front is moving eastward across the islands this morning. The frontal boundary has already cleared Kauaʻi and is approaching Oʻahu. Light and variable winds, along with drier conditions, will fill in behind the front as it passes across each island today. Although drier conditions are expected across the islands on Saturday, there may be a few more rounds of light to moderate rain on Sunday and Monday. As the storm system moves out of the region, trade winds are not likely to resume right away, and a land breeze/sea breeze regime will dominate the region throughout the upcoming week. Key points As of 6:00 AM HST on Friday, April 10: Conditions are improving across Kauaʻi behind the front. Conditions will gradually improve across each of the rest of the islands as the last push of heavy rain associated with the front moves eastward today. Lighter and more variable winds will settle in behind the front, but isolated downpours will still be possible with the lingering moisture. Although conditions are likely to be benign on Saturday, a few more rounds of light to moderate rain showers are likely to push through on Sunday and Monday. Light and variable winds will linger through the end of the week, resulting in very humid conditions despite the lack of rain. Trade wind conditions may begin to settle back into the region over the upcoming weekend. Forecast synopsis As of 4:38 AM HST on Friday, April 10: From the National Weather Service office in Honolulu: A low northwest of the state will swing east before lifting north today and be absorbed is a stronger, nearly stationary, low far northwest of the state. A front just west of Kauai associated with the low will move eastward pushing a broad band of showers eastward across the state through the day. Strong southerly winds ahead of the front will shift over Oahu this morning with light westerly winds filling in behind the front. Drier and lighter winds are expected to fill in across the state Saturday as the front pushes east of the state and weakens. Chance of showers will increase again across the state Sunday into early next week. Land/sea breezes will dominate much of the weather pattern next week as the low remains north of the state. Weather risk outlook As of 3:00 PM HST on Thursday, April 9: NOTE: An updated risk outlook will be posted later this morning.
