卡尔克苏河在白橡公园附近连续数日上下波动、时而超过洪水警戒水位后,预报人员延长了关注时段。美国国家气象局11月3日发布的延长期限,将此前周三中午的截止时间改为持续至周五深夜——对这条河流的关注时间更长;所列洪水影响包括路易斯安那州卡尔克苏县的古斯渡口路发生轻微洪水。1 2 12 19
这一变化对使用该道路的人意义重大,但并不能证明路面是否被水淹,也不能证明道路是否已封闭。截至中部标准时间2026年11月4日周三凌晨2:44这一报道截点,最近查到的警报所列有效时段涵盖了该时刻。是否有后续修订或取消,以及道路状况如何,均无法通过完整核查和独立确认获得结论。
延长警报于中部标准时间11月3日周二上午9:06发布。气象部门的文字确认警报已延长;一则次级转载的标题为“洪水警报现已生效,持续至周五深夜”。WarningVector的相关记录将预计结束时间列为周六(11月7日)开始时的中部标准时间午夜。这是最近查到的所列结束时间,并不保证没有后续通知对其作出更改。12 19 8
警戒水位,不是道路检查
在白橡公园,气象部门将洪水警戒水位设为2.0英尺。其影响说明称,水位达到该高度时,古斯渡口路将发生轻微洪水。这指出了一处具体的易受影响地点,而不仅仅是说县内某处河水上涨。但影响阈值并不等于对道路进行检查、发布封路令,也不证明整条路线都无法通行。1
周日最初发布的警报称,当时正发生轻微洪水,且当天早晨河流水位恰好达到洪水警戒水位。之后的观测值降至警戒水位以下。因此,尽管预报人员继续警告可能再次发生轻微洪水,但这一变化过程不能证明从周日起一直持续有观测到的洪水。1 3 2
河流与警报
预报也发生了变化。周日发布的通知预测,周一早晨水位最高将达到2.1英尺;这是预测值,不是实测洪峰。周一的更新将预测最高水位下调至未来几天的2.0英尺。周二的延长警报再次预测会发生轻微洪水,但没有核实更新的洪峰数值及其出现时间。1 3 2 12
一份较新的次级水位报告显示,到周二深夜,河水可能再次超过警戒水位。Floodriskhere的白橡公园页面(标识为CWOL1)报告称,11月3日中部标准时间晚上10:35的水位为2.14英尺,高于洪水警戒水位0.14英尺。该观测时间比周三凌晨的报道截点早约4小时10分钟。该读数未与第一手水位站数据独立核对,不应将其表述为截点时河流的确切水位。14
Waterline报告称,11月4日中部时间凌晨12:20,古斯渡口路另一处水位站CGFL1的水位为1.88英尺,24小时内上涨0.25英尺。这些数字并不是同一地点、同一时刻的互相矛盾的测量值。它们来自不同的水位站和观测时间,且两份报告都没有说明道路本身是否被淹或封闭。17 14
两个时钟,都不代表道路已畅通
警报记录中还包含两种不同的截止时间:消息到期时间和预计事件结束时间。混淆两者可能会造成虚假的警报解除信息。例如,周日最初的记录将当晚中部标准时间10:15 p.m.的消息到期时间,与预计于11月4日周三中午结束的警报并列。这些字段不应被视为可以互换的洪水危险结束时间声明。5
11月3日的延长尤其清楚地体现了这一差别。WarningVector列出的消息到期时间为中部标准时间11月4日周三上午10点,而预计事件结束时间则是周六开始时的午夜。周三凌晨2:44的报道截点早于这两个时间。这支持一个较窄的结论:最近查到的延长期限涵盖了该截点;但不能据此更广泛地声称所有可能的后续取消都已排除。8
另一个次级列表还存在版本对应问题:它将周一上午的更新时间戳与前一晚的发布和到期时间放在一起。由于未核实原始警报字段,这些记录无法证明气象部门最初的警报存在技术错误。对读者而言,更重要的是,后续延长取代了旧的周三中午截止时间;挑选较早的到期字段无法确定当前状况。6 8
可以得出的结论很直接:预报人员延长了关注时段,但道路实际受到的影响仍未得到确认。没有证实哪一段道路被淹、封路时间、重新开放时间,也没有确认县政府发布过道路状况通知。接下来值得核查的是最新警报是否被替换或取消、白橡公园的第一手观测,以及古斯渡口路的状况。警报时间表告诉人们预报人员预计需要关注多久,但并不能告诉他们前方路面是否畅通。

- The Calcasieu River reached its two-foot flood stage. Forecasters have extended the warning near White Oak Park through late Friday night, with Goos Ferry Road identified as vulnerable to minor flooding. But that river measurement came Sunday. The practical question now is whether the road has actually flooded, and whether the warning has changed again.
- The warning covers the river near White Oak Park in Louisiana's Calcasieu Parish. At that location, the National Weather Service sets flood stage at two feet. Its impact statement identifies minor flooding of Goos Ferry Road when the river reaches that level.
- The weather service extended the warning Tuesday morning, November third. The new wording forecasts minor flooding and carries the warning into late Friday night. That moves the stated end beyond the Wednesday-noon deadline in the earlier notices, giving people using the road a longer period of concern.
- The original warning pointed to noon Wednesday, November fourth. Tuesday's extension moved that stated end to late Friday night. That means midnight as Saturday, November seventh, begins.
- The river has moved above and below its flood threshold during this sequence. Sunday's original warning described minor flooding as occurring. It also predicted a maximum of two-point-one feet Monday morning. That number was a forecast, so it shouldn't be treated as a measured crest.
- The river measured two feet Sunday morning, then one-point-two feet that evening. By Monday morning, it measured one-point-eight feet. That was two-tenths of a foot below flood stage. Those observations show the river wasn't continuously above the threshold.
- Monday's update also lowered the predicted maximum from two-point-one feet to two feet over the next several days. Forecasters expected the river to move up and down around flood stage. Tuesday's extension again forecast minor flooding, without a newer confirmed numerical crest or crest time.
- Goos Ferry Road is the specific access concern. The weather service's two-foot impact statement describes minor flooding expected at that river level. Drivers still need actual road conditions to know whether they can get through.
- A newer White Oak Park reading puts the river above the threshold again, but the figure hasn't been confirmed against the primary gauge feed. The reported level was two-point-one-four feet late Tuesday night. That's fourteen-hundredths of a foot above flood stage, several hours before the early-Wednesday status check.
- White Oak Park's reported two-point-one-four feet and Goos Ferry Road's reported one-point-eight-eight feet came from different gauges at different times. The Goos Ferry Road gauge had risen a quarter-foot in twenty-four hours. These measurements can't be substituted for each other.
- The White Oak Park observation belongs to Tuesday night, before the Wednesday check. It was about four hours and ten minutes old at that point. Both newer readings are dated secondary gauge reports. They provide context for the river's movement, while leaving its exact level at the check time uncertain.
- The warning's message expiration is separate from its stated duration. Earlier notices paired shorter message lifetimes with a Wednesday-noon warning end. Tuesday's extension pairs a Wednesday-morning message expiration with a warning duration reaching the start of Saturday.
- Those separate fields explain why choosing an old expiration timestamp can't settle whether the flood hazard ended. One secondary listing also mixed details from different updates. Tuesday's confirmed extension provides the clearer change in the warning timeline.
- Tuesday's extension covers the early-Wednesday check and states a duration through late Friday night. Whether the warning has since been revised is still unclear. Goos Ferry Road's actual condition, including whether water is covering it or it's closed, remains unconfirmed.
